Reluctant 737, you beat me to it, I was told a similar story by my Instructor in Blackpool once,
In a Glider you look up and see a Cessna 172 and think thats flying,
The Cessna Pilot looks up and sees a Twin Prop and thinks thats flying,
The Twin Prop Pilot looks up and sees a Jet and thinks thats flying,
The Jet Pilot looks up and sees the Space Shuttle and thinks thats flying,
The Space Shuttle Commander looks down and sees the Glider pilot and turns to one of the other Astronauts and says 'Now that's Flying'
Whatever you fly, enjoy it
