Here are some screenshots of me ascending to 10 million feet in a special aircraft (That has a warp drive) called the Ex2 Warpstorm.

At high altitudes, jets and propellers have no thrust. When the aircraft hurtles through space, its orientation does not matter, unless if it is about to do a warp jump.

We ascend!

5 Million feet.

HUD numbers for your viewing pleasure.

6 million feet.

10 million feet!

And now we descend!

HUD numbers in the beginning of the descent.

3 million feet.

I got to a normal height at a location that was about 300 miles away from the islands.
