Great thread. I recall dropping into Stansted several times in the late '70s on LAAS organised coach trips to the Mildenhall Air Fete - yep, certainly remember Maersk 720s and Sterling 727s! Also those Turkish AF Viscounts shoehorned into a hangar on a visit sometime in the early 80s. A couple of THY 707s in '75 TC-JAM was one I think...
