Must have amassed considerable time in that period between lift-off and safety speed in the Anson, Valetta, Marathon, Hastings before arriving at the RAF's first Perf A aircraft - the mighty Bev! Then back to the 'waiting' in aaaaaahhh DH's Devon. It was one of those things best characterised by the FAA's reported utterance after a successful catapult launch - "Thank you God, I have control now!"
