Can passenger planes fly upside down?
Unlike military fighters, commercial planes do not have the engine power for sustained inverted flight and rely on lift from the wings. Commercial airliners are only tested and certified for upright flight.” However, one Boeing aircraft has flown upside down – twice! It happened in August 1955.
Can a 747 do aileron roll?

What happens if a plane goes too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …

What happens to the fuel tank when an airplane rolls upside down?
When the airplane rolls inverted, the header tank is now above the engine, and fuel gravity-feeds from the header tank to the fuel pump. A check valve in the line from the main tank to the header tank stops fuel from draining back into the main tank when the airplane is inverted.
