It's a similar problem with airliners, They have service ceilings where they can no longer create enough lift to climb even though they're under power. That's why you would be hard pressed to ever fly a commercial airliner above 41,000'. They just don't go higher easily, there's some climb left in them but it would take too long. Ever notice when flying that the aircraft has a slightly nose-up attitude when flying level at higher altitudes? It has to at those levels because it's lost a bunch of lift component.
