maintain depth

Airplanes as they go higher in the air ARE affected by the air density. As they go higher in altitude they either have to go faster OR increase thier angle of attack (the airflow vector vs. cord line of the wing). Eventually GRAVITY overcomes the lift vector and the airplane wing stalls.

Here we go again
