All pilots I know are afraid of heights. Airplanes have a floor. Altitude is not height... unless you are standing at the open door with (or without) a parachute. ;~D
Yeah. Flying level ok. Going up though (my cliff)...I start out on an aisle seat clutching the arm rests. After we are up I can look out. Coming down Eddie has to move or I'll be in his lap. I love to watch everything get bigger and closer and stopping a real rush.
