Airliner flight deck training flights in the 70s and 80s.

I remember seeing the Monarch 1'11 just before it departed STN, back to Hurn I believe? With very temporary looking skins blind riveted to the belly.
Growing up next to STN in the 70's the Qantas 707's, Invicta Vanguards, TMAC CL44's and various Britannias pounding the circuit are fond memories.
