the glass door of the cockpit closes and the crew gets away from the plane, you look out the window and wait for one of the engineers to signal that you are ready for takeoff, while you wait you make sure all is well and not broken to prevent later problems in the flight, soon enough a message comes through your radio
"Messerschmitt-262 no.3 you are clear for takeoff, you know the drill."
