During my Navy time I was a Radar Operator at Culdrose, HMS. Seahawk, in about 1952, on a coastal Radar station at Gunwalloe. Directing Naval aircraft interceptions and the like. I often had the chance to watch a landing by a 'Tiger Moth' onto an improvised deck, constructed on an articulated aircraft transporter vehicle, called a "Queen Mary" - I think. Practice after practice eventually got it right, in preparation for a Royal Naval Air Day at Culdrose. Unfortunately : When all was eventually perfect, the driver of the "Queen Mary" finally put the brakes on too soon. The resulting crash wrote off the 'Tiger Moth' and most of the "Queen Mary" tractor unit, just one day before the air day. Although there were no casualties, there was plenty of dissappointment.
