My memory is telling me there was a check on the VC10 which involved re-setting flap CBs prior to TOD - so presumably they were isolated at some stage after flap retraction in the climb ...
Secondly, the flight deck hose-pipe vacuum cleaner story certainly was true - I used to know who it was but grey matter fails me now ...
... and the VC10 did have a wiffle-tree (some call it whiffle) ... it was in the feel system, and provided the same feel to the system by a mechanical linkage between the two feel units if one unit failed.
Finally, in response to the original thread topic, my logbook tells me (rather oddly) that I was positioned out on that very same (G-ASGG) SVC10 under the command of C (was it Colin?) Middleton-Stewart from LHR to FCO on 21 February 1973, as part of a crew to operate back G-ASGL as QG (?) 6122, two days later.
Aahh, memories of Rome, Northbound ...
"a fresh crew takes over here..."
