I thought that Dr Hunt's assistant should really have been in a period uniform, complete with correct hosiery. BEags would have liked that
Too right! Period WAAF shirt and webbing, ooh yes....
I agree about height keeping. Although the pilot flew very accurately, I would have thought that a rad alt might have been advisable. The weighted dangling string idea would have been just as unsuccessful as it was in 1943 when it simply flew more or less level with the aircraft due to drag on the weight and string.
Perhaps PN might remember as he was probably around at the time, but surely the
Upkeep weapon was only spun up shortly before the attack run. I seem to recall having read (or maybe I saw it on TV) that the rotation caused massive vibration through the airframe when the weapon was at pre-drop rotational velocity.
