Ref the Wessex in the Belslow. In 1970 we took ten Wessex out to Singapore as part of exercise "Bersatu Padu". It was possible to get two Wessex (Wessi?) in a Belslow, so five aircraft loads. IIRC, at one point we had two flying at Changi, two in a tech Belslow at Gan, two ditto at Masirah, two ditto at Akrotiri, and two (you guessed it) ditto at Brize. Admittedly, all eventually arrived. Great crew transporter though.
