Well I never!
Chris Powell was of course ex-Ferranti and I believe a former Commando role driver in the RN. He went on to fly for Gallifords (G-BAKS) before joining Ferranti in 1976. Evidently he moved to Aberdeen in 79-80 where he became S76 fleet manager with BCalH after Speechless Two (who formerly held this post) moved on to assume the fleet manager's role for the 214ST.
