Ah the CL44. A purpose built freighter that could carry 27.5 tonnes - or fill it up with fuel and it would still carry 12 tonnes - for over 16hours nonstop at 280ias - some range- some war stories. The last one flying (G-ATZI for TMAC veterans) was written off in an accident a couple of months ago. The Guppy however lives on and every effort is being made to get it back working again. There is an active 'Swingtail Association' for those associated with this great freighter aircraft.
