IIRC one of the navs on 30 Sqn (68-70), Alan Barker, had spent his first tour in Aden flying on a Dakota with the comm' sqn, 66-67.
My late father-in-law was a 'boffin' at Farnborough and again IIRC he went to Kemble in early '73 to see if a Dak they had there was suitable to be used at Farnboro' on some trial he was involved with. I'm sure it was found suitable and it was moved there from Kemble.
