On my E1 plane desc. i sayd that it can reach really high altitudes, but its not normally so here's how to do it:
- Climb to 90,000ft in a 20-40 degrees angle without touching roll, pitch and yaw
- When you reach 90,000-100,000 turn off the engines and hold the airbrakes until you're pitching donwards on a -20 degrees or higher angle
- Turn on the engines and descend to 50,000ft so you can control the plane
- Mission complete
