I thought about going to this, but luckily my Wife was ill so we couldn't
By all accounts it seems that the Passing out displays at Shawbury we did in the late '80s had better 'role demos' (abseiling and roping rock apes, pickup and deployment of USLs, etc, etc) and a more populated flying display than this did, and this was just for the benefit of the course passee's families.
I was also involved in the '88 Finningley Airshow and remembered that it was run almost like, well, um, a Military Operation!
(I had 15 walking cones from Swinderby and a Car park all to myself...)
