That must have been an instructor in the back waving who knew you would be there , fantastic pics
Thanks. Those photographic spots are very well known to aircrew. Weather permitting Mon-Fri there is probably a snapper(s) somewhere on that point and several others. The waiving images were taken at the Bwlch which has three main photographic levels. Some of the guys/girls wear reflective vests so as to be noticeable to the aircrew. Sometimes you'll get 'two-fingers' to denote that they will be coming back round for a second pass.
