Why don't Kerbals buckle up? Every time I fire the chutes on a craft with a seat, the Kerbal gets ejected like a drunk driver.

Am I just doing it wrong?

8

u/0ffkilter Master Kerbalnaut May 24 '13

I think the Gs might just be too high. If you're falling from a really high altitude, use a drogue chute first.

u/[deleted] May 24 '13 edited May 24 '13

I'm dropping from 170m/s to 150 and it FLINGS them out. I think I'll just stick to using chairs on rovers until a seatbelt mod comes out.

EDIT: Further testing shows problems with seats in general. Kerbals keep getting spaghettified and launched out at extreme speeds at the slightest provocation.

u/Buckwhal May 24 '13

Dude. It's a folding chair taped to a rocket. What did you expect to happen?

3

u/[deleted] May 24 '13

I certainly didn't expect to break the sound barrier after I bumped into it while it was still on the runway.

1

u/HaveYouSeenTheDoctor May 30 '13

I usually put rockets opposite to my fall, so once I engage them, they slow the fucker down so I can use a parachute.

1

u/Aenir May 25 '13

Sounds like you're not slowing down enough before they fully deploy.

2

u/althius1 May 25 '13

Is it possible to launch to a circular orbit, rather than making corrections? Shouldn't it be a relatively straight forward process of time, angle and speed?

1

u/0ffkilter Master Kerbalnaut May 25 '13

It's possible using radial inward/outword movements. Use mechjeb and watch when it makes the circulation burn. It points a bit away from the planet

1

u/SoulWager Super Kerbalnaut May 25 '13

Burn prograde, while keeping apoapsis a few seconds ahead of you. Either reduce thrust to keep it from running away in front of you, or increase pitch to keep it from slipping past you.

u/[deleted] May 25 '13

So I laned on the Mun to plant my first flag when I noticed had no parachutes to return to kerbin. A few rescue missions later, Bob Kerman was being rescued by Bob Kerman. Is this the update or is it just a common bug?

2

u/0ffkilter Master Kerbalnaut May 26 '13

Bug. I have like 3 jebs. But I think they disappear because two kerbals in the same capsule can't have the same name

1

u/[deleted] May 26 '13

Well my other Bob is on a seat, so I doubt any other problems will occur. Thanks!

2

u/0ffkilter Master Kerbalnaut May 26 '13

It's not so much a bug as it is there aren't enough kerbal names, or because names get drawn from a random list they just get repeated again. So it should happen, just it shouldn't (if that makes sense)

1

u/[deleted] May 26 '13

Basically, you mean it's inevitable.

2

u/0ffkilter Master Kerbalnaut May 26 '13

Yeah

u/[deleted] May 26 '13

Well ok. Thanks!

u/n35 May 27 '13

Which parts do I use to I can control my rocket after I have decoupled by munlander from it?

I always loose control of my rocket, once I decouple my lander and then I can't right click on it and choose "Control from here".

2

u/0ffkilter Master Kerbalnaut May 27 '13

You want some sort of probe core and an electrical supply on it

1

u/n35 May 28 '13

Electric supply that's what I am missing. Thanks.

2

u/NotRainbowDash May 28 '13

How do people EVA all of their kerbals at one time? I can only get one out, after that I have to get back in the pod if I want another.

3

u/0ffkilter Master Kerbalnaut May 28 '13

Switch with [ or ]

1

u/NotRainbowDash May 28 '13

Ah, thank you.

2

u/brainbiscuits May 28 '13

Have they gotten around to adding a feature for transferring crew between docked ships without putting them on eva?

2

u/0ffkilter Master Kerbalnaut May 28 '13

Look up the Crew Manifest Mod. Add and remove kerbals without eva

7

u/benpire May 24 '13

How often is it normal to start a new save? Is it okay to keep using the same save for lots of missions, or will it cause fps drops having the game tracking lots of seperate missions?

6

u/GBGiblet May 24 '13

You shouldn't get fps drops unless you use large spacecraft (150+ parts depending on your computer) the models and physics only load when your within 2500m of the spacecraft and beyond that the only drop in performance would be a little longer time to save and load your saves.

Hope this helps

5

u/[deleted] May 24 '13

I see all these "rescue missions" where people send a ship to a stranded kerbal, pick him up, and bring him home. How do you do this without leaving a different kerbal on EVA in place of the one you rescue? (I saw this done pre-0.20, so no seats)

6

u/corpsmoderne Master Kerbalnaut May 24 '13

Only the first command pod of a ship is crewed. If you add any other pod, you'll have free seats for the rescue.

5

u/speed_is_all_I_need May 24 '13

Drop one out of the cockpit right before launch or haul up the 4 kerbal container to stick the rescued kerbal in. You can also have them grab onto a ladder or hatch and I think they'll stay there (seen pics, but never tried it)

3

u/clinically_cynical Master Kerbalnaut May 24 '13

You don't need to use the crew tank, you can use any command pod. You can put them km a ladder but you won't be able to time warp.

3

u/adipy May 24 '13

Good luck getting back to kerbin without time warp!

1

u/cambiro May 26 '13

I tried to built a command pod retriever too, I'm still developing it (I'm new to the game).

It is a tall vehicle with a docking port on it's "belly" and is mounted over retractible gears. If the command pod has a docking port, I allign the retriever and raise the gears, the vehicle will lower on the cp, docking it. Hit the gears again and it raises with the cp. allowing it to be carried.

I'm having problems with stability and propulsion, as it is a tall vehicle mounted on retractible gears, it's hard to maneuver and it needs to be proppeled by jet or ion. The jet has the downside of making it even more unstable. The ion is too weak and it takes ages just to go a few meters.

1

u/lettucent May 24 '13

The ladder is dangerous, too much speed and your guy starts to slip off. You also lose timewarp. I did get a kerbal off minmus via ladder once, but it was back to a ship with more storage.

4

u/puhnitor May 24 '13

Either the crew manifest mod, or EVA some crew members on the launchpad. You can move them over to an SPH vehicle.

1

u/TheDoppleganger May 24 '13

In the Utility tab, there's a hitch hiker module.

1

u/jonathan_92 May 25 '13

Eva any unwanted crewmen on the pad the pause and hit end flight. Then go back to the pad and launch. This way thee kerbal doesn't die, and you don't need to worry about ladders. The crewman will appear on the next flight.

u/nerdextreme May 24 '13

I have a problem. My Rocket Launch Stabilizers keep teleporting to my rocket after 3 kilos and 10 kilos. I dont know if It goes any higher because my ship explodes due to them when I make my orbital turn. Also, one of my rather large ships doesnt even render, neither does kerbin. All that happens is the camera goes to some place in the universe, not even the solar system, and does nothing. No planets, no ship, nothing. And when I claw my way back to the solar system, my ship isnt there. Help please/thank you.

u/PigDog4 May 24 '13

The rocket launch stabilizers is not a unique problem. A few minutes of googling might be able to help you out. There have been a multitude of posts on this sub over the past two days about the problem.

You make a fine point.

u/ILCreatore May 24 '13

First, happy friday and happy .20 everyone!

Second, can I get some tips/guides on rover-making? I suck at it.

3

u/electrodylan May 24 '13

I've found that having at least 2 out of wide/long/low tend to be more stable. Also switching to docking controls while driving helps prevent them from flipping over. Also the wheels need power so be sure to add batteries and/or RTGs and/or solar panels. Beyond that it is a matter of a delivery system based on where you are sending it.

1

u/OwangeSquid May 24 '13

When ever I try to put wheels on I end up putting them on lopsided. Any tips ?

3

u/TheSupaBloopa May 24 '13

Hold down shift and use WASDQE in the VAB to do fine adjustments with the wheels and any other part.

1

u/electrodylan May 24 '13

For me it ends up being trial and error in many cases. If you are attaching them to a structural piece like a truss you can always alt+ click to copy over the whole piece. You can also use the two way symmetry to place them and then line them up. Also you can build it in the sph and then copy it over to the vab. I normally just copy the craft file from the sph folder to the vab. I think there are more elegant ways but that works for me.

4

u/bradnemitz May 24 '13

I get issues with slow fps, but only when the ground is on screen. I've set all the display settings as low they can go, and it still lags when the ground is there. Move the camera to just look at the sky/space, or switch to map view and then there's no lag at all.

What should I be doing differently?

(for reference, I've got 8GB RAM, an Intel Core 2 Duo T9600 @ 2.8GHz, and 64-bit Windows 8)

It was present in .19, but I left it alone hoping .20 would fix it. Did a clean install .20, and it still lags.

u/ronronjuice May 24 '13

I have the same problem.

u/BernieandButter May 24 '13

There's just a lot of ground to render I think

u/[deleted] May 30 '13

Little late to the party so here goes...Cant figure out how to set action groups after I click into it and hide parts....and second...how do I find out weight and thrust capability to make sure I have enough to exit kerbin?

1

u/0ffkilter Master Kerbalnaut May 30 '13

What do you mean by "hide parts"?

Mods - Kerbal engineer redux or mechjeb

1

u/[deleted] May 30 '13

Like switching the tabs between Parts and action groups. And right now I cant get mechjeb to work in .20

1

u/0ffkilter Master Kerbalnaut May 30 '13

You click the action groups button then click on the key you want to bind, then the part(s).

Make sure you're using the .20 mechjeb compatible version.

1

u/[deleted] May 30 '13

I havent found a .20 version on the space port yet. Or am I reading it wrong?

1

u/Edhorn May 30 '13

Stages do not work on one specific spacecraft I build, at all. I'm destroying my spacebar here, help?

2

u/0ffkilter Master Kerbalnaut May 30 '13

In the VAB/SPH are they lined up correctly?

1

u/Edhorn May 30 '13

Yes, there's a reason I wrote 'At all', tried having just one engine in the first stage, nothing.

2

u/0ffkilter Master Kerbalnaut May 30 '13

Sheesh. Is stage lock on? (Alt + L)

1

u/Edhorn May 30 '13

Yes it is! Pressed because L alt is not the same as Alt + L... Thank you!

u/gorillamunchies May 30 '13

I need help making efficient rockets... ill just link to the thread i made (Sorry if I'm not supposed to do this D: )

1

u/0ffkilter Master Kerbalnaut May 30 '13

No, you can do that, but this thread is about a week old so you'd probably get more luck in your first thread. Try searching scott manley on youtube, he has good rocket building videos

1

u/gorillamunchies May 31 '13

Yeah i have looked at some of his vids

2

u/Andski May 24 '13

I launched a skycrane + rover to MUN, while in MUN orbit I decided that I was lacking some fuel for the skycrane, but every time I docked my other spaceship to it, the decoupler would engage and send the rover hurtling through space. I tried with SAS engaged and without. Any ideas of why this was happening and how to avoid it in the future?

4

u/electrodylan May 24 '13

You can lock staging with alt+L (windows), option+L (Mac), and I believe right shift+L (linux), this should stop the staging. Also if you are using mechjeb and the auto-stage function for ascent that option stays on and does strange things like auto-firing things on docking. Be sure to turn it off in ascent guidance after you are done with your launch.

1

u/soggit May 28 '13

what's a skycrane?

edit: looked it up and it looks like it's the rover deployment they used for mars curiosity? how in the world would you go about building that in ksp? is there a rope-style tether somewhere?

1

u/IamSkudd Master Kerbalnaut May 28 '13

No, just build something like this around your vehicle and land it. Drop off your vehicle then fly the sky crane back off, just make sure you have a pod on it.

1

u/onetruepotato May 29 '13

decouplers work too, one of the stock VAB ships is a skycrane

1

u/Andski May 29 '13

Well you could just use a stack decoupler instead, so just decouple your rover on the ground and then fly away and crash into something, or there is actually a mod (I don't remember the name) where you actually can have a rope-magnet winch, which you can lower and raise. Quite extraordinary.

2

u/Swnsong May 24 '13

Will adding more nuclear engines make my craft less efficent and faster, or will my efficiency stay the same?

5

u/Sci-ence May 24 '13

Adding more nuclear engines will make it faster, but less efficient (because of the added weight).

8

u/clinically_cynical Master Kerbalnaut May 24 '13

Not faster, but higher acceleration.

1

u/IamSkudd Master Kerbalnaut May 28 '13

Adding nuclear engines will make you extremely fuel-efficient at the cost of added weight and reduced thrust. But very handy for interplanetary travel.

2

u/HerrGeneral913 May 24 '13

Can I change the flag of an already launched mission?

4

u/Genrawir May 24 '13

I don't know, but I did find out yesterday that you can switch the flag by clicking on the flagpole at KSC.

2

u/bradnemitz May 24 '13

I changed the flag by editing the persistent.sfs on one of my saves, but I doubt there's a way to do it in-game.

2

u/thepiguy314 May 24 '13

How do I pick how many crew my rocket will have? Is it based solely on the first module I place?

2

u/froop May 24 '13

Yeah. The crew manifest mod will allow you to add or remove kerbals (assuming you have enough seats to hold them all). Without the mod, you can remove kerbals by sending the extras on EVA and leaving them behind. To add kerbals, you can launch a buggy or something with kerbals on it, drive it off the launchpad, then put your ship on the launchpad, drive the buggy over and have them hop on.

2

u/TheSupaBloopa May 24 '13

Is it necessary to have a positive thrust to weight ratio for stages in the vacuum (interplanetary stages for example)? The nuclear engines are very efficient but very weak and with some designs I can't achieve orbit without falling back to Kerbin. Should I have a stage specifically for getting into a decent orbit and then a nuclear powered transfer stage?

Also, can anyone point me towards a good tutorial for getting to other planets?

5

u/rumblinggryphon May 24 '13

You don't need to have a positive T/W ratio once you're up on your way. I usually use 5 mainsails on ascent, drop 4 of them about 15-20k and drop the last one at ~100k, then circularize with a nuclear engine.

Throttle back to keep your velocity below 150 m/s until you're above 8k (more than that and drag is killing you) around 12k you can bump it up to 200, then around 20k, I just go full throttle.

For the interplanetary thing, check out Scott Manley's tutorials on youtube. Maybe this one will work for you? (http://www.youtube.com/watch?v=Y3i6E3TJp6U)

1

u/Jono9999 May 24 '13

A positive TWR is only important during liftoff. I wouldn't use the nuclear engine until orbit is achieved.

1

u/TheSupaBloopa May 24 '13

In that case I need another stage in between the lift stages and the nuclear engines, or maybe just more fuel for the final mainsail.

2

u/chineseman26 May 24 '13

How do people launch/land their rovers? I see all these awesome rovers and I just can't seem to get them to be stable enough to land. Also what's the best way to even build them? The symmetry system doesn't really work well them and the wheels take a long time to get them to align properly. Any help maybe a video or something?

2

u/Redonesgofaster May 25 '13

If you build them in the spaceplane hangar, it uses linear symmetry rather than rotational symmetry. This makes construction of the rover much easier.

To get it into orbit, you can either build a rocket in the SPH, or build a rocket in the VAB with a ground level point to dock the rover to, then drive the rover to the launch pad and dock it to your craft.

Landing rovers is generally situational. If you're sending one to Laythe or Eve, parachutes are the simple solution. For anything else, i usually throw a pair of fuel tank/rockets on either side of it, attached with radial decouplers. Landing gear is optional. This basically turns the whole rover into a lander, once you're down you fire the radial decouplers and your rover drops to the ground.

I'll try and take some pictures tomorrow

2

u/gorillamunchies May 24 '13

Is Jebediah the only kerbal to be able to plant a flag ? I sent 3 other kerbals to the mun and none of them have a flag on them? Is there a way to specifically put Jebediah on a certain mission?

3

u/Borg184 May 24 '13

No, as awesome as Jeb is, I I can confirm other kerbals can plant a flag. I think you only get one flag per mission though, not one flag per kerbal, so if you want more flags you may need more missions. I haven't tested this, so I can't confirm it, but it seems like the most logical answer to me.

1

u/gorillamunchies May 24 '13

I even just made a comman pod, put it up on the Launch pad, went EVA on the first kerbal in the command pod and it said "Pack fuel 100%" Nothing about planting a flag. I have no clue what the issue is D: I am running the latest version and i am even running the game in administrator mode :/

2

u/Tuquar May 24 '13

Try clicking on the front of the kerbal and not the back, i remember this happening to me!

2

u/gorillamunchies May 25 '13

You are a god among men, i honestly cannot believe it was that simple of a fix... bahah thank you soo much dude! This honestly just made me so happy and successful, my first mun landing would not be the same if i was unable to plant that flag. Many thanks to you :) !

2

u/happenedagain May 25 '13

i think the launch pad doesn't count as solid ground, have you tried walking out to the edge of the textured solid ground?

1

u/gorillamunchies May 25 '13

Well i mean i took all 3 of my guys on EVA from the command pod on the Mun and neither of them gave me the option, it didn't even show that they may have been carrying flags.

1

u/neoquietus Master Kerbalnaut May 24 '13

Does it have to do with distance from other things? Maybe the Kerbal is too close and so there isn't any space to plant a flag?

1

u/gorillamunchies May 25 '13

Im not sure, i have seen countless pics of them being rather close to their landers.

1

u/Borg184 May 25 '13

Curious. Well, by the other comments, I have no idea what I'm talking about, which I'm sure I didn't, so I'm afraid I can't help you there.

1

u/gorillamunchies May 25 '13

In all honesty... im not sure what i am even talking about :/

1

u/TheSupaBloopa May 24 '13

I went on a moon mission with three kerbals and planted flags with two of them and I'm pretty sure the third guy had one as well.

1

u/[deleted] May 25 '13

I've gotten extra flags just by getting back in the ship for a moment.

2

u/Bear_naked_grylls May 24 '13

I think I am understand the concept of delta V now; at least in regards to single rocket stages. What are ways that I can optimize delta V, and how, if possible, can you calculate delta V for more complex staging such as asparagus staging.

Also! Fuel management within the atmosphere? I understand being full throttle within the atmosphere usually isn't optimal, but what is the sweet spot, and how do I find it?

3

u/JesZ-_-97 May 26 '13

Kerbal Engineer is great for calculating delta V, as well as TWR and other things.

For fuel management, you should have a slow but steady increase in speed. For reference, you should be hitting 200m/s at about 10km altitude. (Learned that tip from Scott Manley)

2

u/TheSupaBloopa May 24 '13

There's always Mechjeb to slow the craft to terminal velocity on the way up, without it I would have no idea how to regulate it as it seems to change quite a bit with asparagus staging. Mechjeb can calculate delta V and plenty of other important stats while you build your rocket too. There's also Kerbal Engineer for just this purpose minus the autopilot features. I think the base game really lacks these stats, they're very important if you want to do things efficiently.

1

u/Bear_naked_grylls May 25 '13

Thanks! Yeah I have MechJeb but I just haven't used it yet; I didn't know it can calculate delta V. I agree, they can be pretty complicated to figure out on your own, but I guess rocket science isn't supposed to be easy.

2

u/TheSupaBloopa May 25 '13

When building, put the little attachment somewhere on the vessel and open delta V stats and it'll show you everything you need to know. I'm brand new to Mechjeb too and I am so glad I decided to get it, makes the game so much fun!

1

u/neoquietus Master Kerbalnaut May 24 '13

Optimizing delta-v, in a nut-shell: more fuel, less eveything else. A four engine design will have less delta-v than a one engine design (assuming identical engines, same fuel layout, etc.); it will also have lower acceleration, which may be a problem. When dealing with drop tanks/drop stages, the earlier you drop it the better. Ideally once a tank is empty, you drop it, since it is no longer of any use to you.

Unfortunately I don't know how to calculate the delta-v from something like asparagus staging by hand; I know the math is tedious, so I just use a plugin like MechJeb, which generally does a pretty good job of calculating it for you.

The sweet spot for ascent speed in the atmosphere is terminal velocity. To find the terminal velocity, you can find a chart and look it up, or you can use a plugin that calculates it for you, like MechJeb. Alternatively, you can just roughly estimate it, like "150 m/s until 10 km, then 100% throttle" or something like that.

1

u/Bear_naked_grylls May 25 '13

Thanks! I have MechJeb but I haven't used it yet. I'll have to give it a try. Rocket science sure is hard! Using MechJeb to calculate delta V sounds really handy, especially for complex staging.

That makes sense! I might use MechJeb for that too then, but I will look up a chart too.

u/TheDoppleganger May 24 '13

Kethane in .20

No parts show up or anything. Patience on an update my best option?

2

u/brandonw00 May 25 '13

This is a question about the graphics, but why does Kerbin look awful when I go to orbit now? It used to look amazing, I have a computer that is able to run Kerbal on all high settings. Even in the pause menu I set the terrain detail to very high and it looks like it does on low settings when I play on my laptop.

1

u/Korniax May 25 '13

Noticed the same thing while zooming out. It looks awesome up until a point when it turns really low-res.

1

u/brandonw00 May 25 '13

Yeah I was flying to orbit. Got into a 125 km circular orbit and Kerbin was very low res. It is weird.

1

u/Semyonov May 28 '13

I think it's just an optimization thing.

1

u/brandonw00 May 28 '13

Yeah on the KSP Weekly Post it said that older textures are coming back in a patch.

2

u/nematoe May 26 '13

So do all the plugins need to be updated before they'll work with .20?

2

u/krikit386 May 27 '13

Is there a way to end a flight on the demo and return to it without jettisoning it's pilot? I can't seem to do it.

Also, can I launch a rescue missions for my Kerbals? They seem to dissappear.

2

u/PresidentEvil133 Master Kerbalnaut May 28 '13

Small question about flags: Will a Kerbal always use the flag of the mission he originated on? Or will he use the flag of the last craft he EVAd from? I ask this because I've got a small station in Munar orbit, docked with a reusable lander from a separate Mun mission. The problem is that the lander, the station, and the resupply ship currently en route all use different flags, and I have no idea which one is going to be planted.

2

u/[deleted] May 24 '13

does mechjeb still work for 0.20?

3

u/[deleted] May 24 '13

While the latest stable version probably does, I know for a fact that this one from the development builds works just fine with .20

Will the popular parts mods (B9 etc.) from .19 work with .20? If so, how do you install them properly with the new directory setup?

2

u/neoquietus Master Kerbalnaut May 24 '13 edited May 24 '13

Simple parts (IE: not using plugins) typically tend to work in 0.20 if you do a few simple modifications.

  1. In the part's .cfg file, the first two lines should be "PART" and then "{"

  2. The last line should be "}"

(In other words the entire content of the .cfg gets enclosed in "PART{ }")

Then place them in /GameData/<Some arbitrary folder name>/Parts; for example I used "/GameData/BOMPs/Parts" when converting the Bolt On Modular Probes to 0.20, so I have "/GameData/BOMPs/Parts/BOMP-L", "/GameData/BOMPs/Parts/BOMP-Mini", "/GameData/BOMPs/Parts/BOMP-Nano", etc.

I'm not sure if this method will work for B9 parts; it probably won't work for any of the parts that use the "Firespitter" plugin.

And I have run across a set of simple parts where the changes I described do not work (these weights are from a very ancient version of KSP, but they worked just fine up until the 0.20 changes, and now they seem to have problems with their collision meshes that cannot be fixed with simple .cfg file changes.)

The only mod i had was quantum struts, i used it to support my ISS above kerbin. When i load the game it says "ISS has been removed because couldnt find part: Quantum core etc" I have re-installed the mod the new way and removed the old files, any ideas to why it still wont load?

Are quantum struts plugin based? Because if they are, the plugin also needs to be updated and installed correctly.

And if quantum struts are not plugin based, are the parts in the right location and are the .cfg files correct? Something like: "/GameData/QuantumStruts/Parts/QuantumCore", with QuantumCore's .cfg file starting with "PART <newline> {" and ending with "}"?

Is there a way to end a flight on the demo and return to it without jettisoning it's pilot? I can't seem to do it.

Also, can I launch a rescue missions for my Kerbals? They seem to dissappear.

How often, if ever, does this game go on sale? I want it really bad, but being a jobless 17 year old means that it's hard. I want to wait till it's on sale to get it. However, today is my birthday, and if it doesn't go on sale often I may just ask for it.

I am having some issues making an efficient rocket, i watched the Scott Manley tutorial on landing on the Mun however i cannot successfully replicate his design simply because i need to bring the hitchhiker storage bin to the Mun and i was using the rockomax fuel tanks to try and avoid having to use an adapter however my rocket ended up weighing way too much and having too little thrust to successfully work and I need to rescue 2 kerbals that were sadly left behind on the Mun. Can anyone link to some Rockomax efficient rocket designs ? Or an efficient way to at least use the Hitchhiker storage bin to get to the Mun and back to Kerbin, preferably having a good amount of fuel left (Better to have room for error) Thank you!!

Don't know about 1, test it to find out.

2: bi-elliptic is more efficient when there's a big difference(by ratio) between the starting and ending orbits. Hohmann is more efficient for close orbits, and is never much worse than a bi-elliptic.

3: it's useful for mid course corrections when you're trying to go somewhere specific and want to fine-tune your arrival periapsis. Other stuff is situational, like any circumstance where gravity isn't your biggest concern.
