Sadly, I saw the opposing side as groundcrew on both CFS and Rects at Scampton, throughout their introduction.
Absolute disaster in terms of interchangeability of parts and servicing.
it wasn't long before we had a number in the corner of the hangar awaiting panels and flying surfaces which (due to their manufacture and figment), just could not be swapped in the regular mode.
Always good to see them arrive on a Friday from Shorts and be parked for the weekend alone, on the far side of the airfield for 72hrs...
got to say, they did get better though...
