Am I missing something? What kind of radar surveillance is needed for a bunch of up round and down operations? Which ATC gliders wandered far enough away from mummy to be of any interest to anyone else? My airmaps clearly show gliding sites (a big double cross) and 'areas of intense gliding activity'. Why would anyone in the GA or RAF wander into these zones except in an emergency. Is there going to be any AEF activity at gliding sites now that all the aircraft are U/S?
Only twice in my career in gliding did we have any intrusions - at Meir a helicopter pilot who was lost and making a precautionary landing in fog - and the day at North Weald when a heavy mistook our field for Stansted (I think our runway might have been longer than theirs) and was down to 400 ft before he realised his mistake. What good was radar doing that day?
