Hope the following isn't too risqué.
When I joined BEA in 1973 and flew Viscounts at Glasgow, one of the pilots was Jock Sneddon, ex Lightnings.
He'd a tale of, upon receiving his posting, 'phoning to enquire of a colleague already on type what performance he might expect.
Jock's account went along the lines of:
"I asked him whit it was like and he said; Well, you line it up, shove it intae reheat an' the first thing that happens is yer foreskin hits ye in the face; by the time ye claw it doon again yer passin' ten thousand feet in the climb!"
