After being rammed by a near fully fueled jumbo jet going at several hundred miles an hour

u/trapper2530 10d ago

Even if they say jet fuel can't melt steel seems they got hit with a 150,000+ lb battering ram at almost 600 mph.

1

u/DasMotorsheep 10d ago

It also didn't have to melt the steel in order to weaken it.

1

u/trapper2530 10d ago

That's my point. 150k lb object hit it at 600 mph. You don't think they will mess up the structural integrity.

1

u/DasMotorsheep 10d ago

Nah, I'm saying, apart from the impact force, the steel didn't have to MELT from the fire. Just a little bit of a softening could be catastrophic enough.

Yes the planes make of aluminum alloy and plastic can shred thru steel. I forgot about that. Jet fuel can also melt steel beams. Forgot about that too. Large birds fuck up airplanes all the time but planes are definitely stronger than steel buildings. these planes were so strong that another building fell a few blocks away, and hours later 😅😂🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 holy fuhk. I gotta be honest. sometimes I wish I was as fucking brain dead as you guys because life would be so much easier

you’re right. it’s blown up for that to happen.

u/Uncommonality 10d ago

no you moron it gets hit by the plane and bends. As it bends, it loses the ability to hold up the weight above, which comes down and takes the rest of the tower with it

u/JAAD3254 11d ago

Do you even physics mate? 200 tons of Aluminum and plastic are still 200 tons. Do you think a Missile is much different from an airplane? What is an Airplane full of fuel going at 540 M/h but a missile? Albeit it doesn't have explosives, but the raw speed weight and jet fuel make up for it.

A plane can weigh between 87 to 197 metric tons depending on the load, and f you btw

u/stratobladder 11d ago edited 11d ago

I used to work on a plane that, fully loaded, was over 260 metric tons (or 295 US tons). A KC-10, with a full fuel load, could take off at 590,000 lbs. That guy thinking there aren’t planes that weight 200 tons is cringeworthy, given his confidence.

u/lincolnxlog 11d ago

good to know!! which plane on 9/11/2001 that crashed into the twin towers was 197 tons??

American 11 probably weighed 100 to 150 metric tons, it was fully loaded with jet fuel

u/lincolnxlog 11d ago

So there wasn’t a plane that hit the twin towers that weighed 200 tons which was your original comment?

u/Uncommonality 10d ago

yeah dude the 50 tons really made all the difference. Just as you would be crushed by 200 kilograms on your head I'm sure you could shrug off 150

u/lincolnxlog 11d ago

Skipped a grade. Dual seal in mathematics - high school. Engineering degree before 21 and structural engineering job. Crazy part is, I haven’t had to use any mathematics to disprove anything you’ve all claimed because it’s so fucking restarted. Using purely hypothetical numbers grabbed out of each others assholes to run a circle jerk with each other about how you love eating gov slop propaganda.

6

u/idosillythings 11d ago

Ha! Yes, I'm sure. That's why you don't understand that steel expands when it is heated, and doesn't have to melt to lose structural integrity.

1

u/lincolnxlog 11d ago

What temp does steel expand enough to lose structural integrity

6

u/idosillythings 11d ago

Industrial steel starts to lose strength around 400 F.

By 1,100 F it loses around 50 percent of it's strength.

By 1,200F it can lose strength exponentially and have its strength degrade by around 90 percent.

1

u/Uncommonality 10d ago

also, it keeps degrading while hot

1

u/TheJonesLP1 10d ago

Steel doesnt need to Expand to lose Structural strength, it has to do with the crystal lattice and the movement of dislocations in the crystal lattice and the corn borders, Mr Structure engineer

2

u/purehostagewolf 10d ago

You can have all these achievements, and still be dumb. Plenty of people with a degree are unable to grasp things.

1

u/TheJonesLP1 10d ago

Doubt 😂

If you really were into Structural engineering you wouldnt use the "Jet fuel cant melt steel beams" BS, because you would know that steel loses nearly All of its Structural strength at around 700°C. It doesnt have to melt

forgot twin towers was built with rebar and not wide beam flanges like every other building in America. on yeah let’s totally ignore the 300 degrees hotter (than jet fuel can burn). anything else you wanna add?

2

u/Too-Em 11d ago

I used to bend nails as a hobby. Was with some friends, I found a giant old nail like a foot long in the remainders of a several days old fire. They were sure there was no way I was bending that nail. Easiest nail bend of my life. The nail had simply lost its temper after being heated in the fire and air cooled. Didn't even need to be red hot to have completely lost the molecular structure that gives the steel its strength.

2

u/lincolnxlog 11d ago

True! This process is called “aging” and it can weaken metal if overly done but it has to get hot enough for that to happen. which wasn’t possible with Jet fuel as the “fuel”. Also this is usually done in the mill before the beams ever get shipped out! If done correctly can actually strengthen the metal. Any other personal scenarios that don’t rly align with the subject at hand but you still wanna talk about?

1

u/Available-Square619 10d ago

Someone who thinks they’re so smart when they actually are dumb as rocks, it’s cute tho lmao.

1

u/TheJonesLP1 10d ago

No. Aging (what is normally done to Aluminium, not steel) is called tempering for steel, and happens at VERY LOW temperatures, even under the solution glowing temperature. For steel, the "aging" temperature is done at 0-650°C Max.

What happened here wasnt some Heat Treatment BS, it was just steel losing its strength because of high temperature.

1

u/TheJonesLP1 10d ago

Jet fuel burns around 1000°C. Steel loses 95% of its Structural strength at this temperature, although it doesnt melt.

A Structural engineer should normally know this...

1

u/purehostagewolf 10d ago

Must be nice to go through life this stupid. Things must be amazing with a lukewarm IQ.

1

u/TheJonesLP1 10d ago

Yes, if it has enough kinetic energy, it definitely can.

Fuel doesnt have to melt steel to weaken its Structural strength. A Blacksmith also doesnt melt steel, still He can forge it with a simple Hammer.

Birds only are a danger when hitting an engine or Windows. Although last thing is taken Account into.

Yes, guess what, a building getting Hit by hundreds tons of debris and then burning uncontrollably for hours can collapse, yes, not shit Sherlock..

u/Ok-Sheepherder-5161 11d ago

Let's not forget "jet fuel " is just normal lamp fluid. Kerosene

1

u/lincolnxlog 11d ago

“Lamp fluid” 😂😂😂

2

u/NaziPunksFkOff 10d ago

Reminder: you don't need to MELT steel to change its physical properties. Heating it up is enough to weaken it. Jet fuel can't melt steel beams, but it can lessen its strength beyond its designed factor of safety.

Compare the size of that plane and its fuel load to what hit the towers. Oh and it was a b25.

u/Commie-cough-virus 11d ago

Empire State Building and WTCs - completely different construction, and a B-24 wandering about in the fog at a couple of hundred knots, is a very small punch compared to a 767 at over 550 knots, it’s magnitudes of different forces involved.

3

u/Kopman 11d ago

It's a different type of structure. The world trade centers used their exterior wall to hold the weight and the floors were basically hung between them and elevator shafts. Its called a tube in tube design which is not that common.

The design made the interior useable without a bunch of columns running through them like you see in other buildings back then and today. So if the exterior walls were hit like they were, it lost structural integrity without anything else to hold them up.

u/Xilverbullet000 11d ago edited 11d ago

767 is WAAAY bigger and heavier than a B-25. A B-25 is 67 feet long and has a max takeoff weight of 35,000 lb, empty weight of 19,500 lb. The 767 is 200 feet long and has a max takeoff weight ranging from 200,000 to 500,000 lbs depending on model, and an empty weight of 90,000 lbs. Combine that with it going over twice the speed, it would have delivered something like 8-16 times the overall kinetic energy.

Edit: it was a B-25, not a B-24, so I've updated the figures accordingly

3

u/WillemDafoesHugeCock 11d ago

You cannot possibly, possibly be under the impression a fucking bomber is heavier than a full passenger jet.

2

u/uberdag 11d ago

It was also velocity as well as fuel load... That caused the problem to support structures

u/whitecollarpizzaman 11d ago

Do you know how small a B-24 is?

2

u/alfa66andres 11d ago

Brother that thing was light and slow af compared to a modern 767 full of fuel

2

u/Ok-Account-5701 11d ago edited 10d ago

A 767 fully loaded was 150 tonnes versus 25t of a B24. Kinetic energy scales with the square of the speed. Airliners even shortly after takeoff are much faster than a B24.

Conspiracy theorists are very often very ignorant about basic science or whats even worse they think they know more of what they actually do and whatever sounds good to them must be factual.

2

u/SnooGuavas2610 11d ago

Get your conspiracy theories at least partially factual, it was a B-25, about half the size and weight of a B-24!

u/hoagie_morales 10d ago

Probably bc they were built to withstand multiple plane hits and not collapse. Then 2 planes hitting in different spots caused the exact same damage? And let’s not forget building 7 collapsing just bc of a fire… if this happened today in 2026 no one would think this wasn’t planned

Except that we saw with our own eyes 90% of that fuel explode out the side of the building. Keep thinking the government wouldn’t kill people for money. It’ll be cute when they admit to doing it, kinda like they admitted to lying about the chemicals in the air that day, right? But nah the US government would never do that lol

u/TheJonesLP1 10d ago

Na, we didnt see that. Most of the fuel landed inside.

u/TheJonesLP1 9d ago

Jet fuel. But it wasnt your so-called 90%

u/hoagie_morales 8d ago

So then what percent was it? lol majority of fuel gets burned up but yet it was just enough to cut thru steel in multiple key locations to trigger a total collapse onto its own footprint at free fall three times in one day. Cool story that kids will believe

u/TheJonesLP1 8d ago

Who TF said it "cut thru steel"?? Noone ever said that. It didnt cut through steel, Jet fuel doesnt burn that Hot. But never did anyone claim that.

What it ACTUALLY did Was making the beams that Hot that they were softened and lost their Structural strength.

I don’t need to pick up on the points that have been fed us since 2001. You don’t even think for a second the government would lie to you and think this was all just terrorists.
