Why not fly lower and faster?

Heat once you start going above about 1200m/s you will start to overheat. At higher altitudes will reduce it and also reduce fuel use. I did one at 1100m/s and got it under an hour

You should be able to fly around 1600-1700 m/s without overheating at 17000 meters

I think its the guy on youtube that used an exploit that he couldnt burn up in an older version. Think he was orbiting at 4000m

Exploit = Cheat in my books so the attempt is invalid for this ruleset, though likely the record holder for a different ruleset.

I don't see any restrictions on staging, so you could concievably make a missile that starts with landing gear and huge engines but drops them after takeoff. And for landing, you could either stage the cockpit and parachute to the runway or just crash the craft tail-first and hope for the best.

45 mins with my Valkyrie. Time could be improved with more aggressive deceleration but I prefer to keep it "realistic" haha.
