ExWtnFTE, rather to my everlasting shame, the company I worked for was one of the main consultants/contractors on the monstrous students' residences which now sully the the hallowed Hatfield Aerodrome. It was a grim and harrowing battle persuading my colleagues that all written references should be to the "de Havilland Campus" but I persevered, generally won the day and am fairly confident that anything that went out via the marketing team used the lower case "d". Certainly if I got my mitts on it... I suspect something I read in "Straight and Level" some years earlier had stoked the vehemence!
Aerohack, apparently VX250's rear end was rescued from the fire dump at St Davids. I seem to recall that another fairly substantial Sea Hornet wreck survived into the 1960s down at Plymouth or somewhere. Oh for a Stephen Grey/John Romain/Glyn Powell/substantial cheque book back then. TT193's rebuild is based around a fairly substantial centre section recovered from Canada.
