Code Blue,
Yes, very "St Exuperian" isn't it. He was the French romantic hero (Author of Le Petit Prince etc) who went missing in 1944 on a recce flight from Corsica.
I have a feeling that it wasn't him, however, and that it is truly anonymous.
The quote was very evident around RAF Operations Rooms and Crew Rooms in the early 50s and it really stuck in my mind. It's too late to change my view now.
But mustn't hi-jack Speedbird's thread. Back to you fellah.
