Autair 748s were leased to many operators- in the winter and almost entirely from 1968 - we rarely saw them a Luton after that when One Elevens meant passengers and crews didn't have to endure long round trips to the likes of Corfu. This was just before I regularly visited the airport but the aircraft is probably back from a winter lease or about to go out on lease. The Viscount next door is presumably British Midlands G-ASED minus the BM on the tail - is that plate a rudder lock or is the photo deceiving? The aircraft looks quite dirty - don't remember seeing it like this. Not sure about the DC3 - it might be G-APPC which languished on the apron for most of the following summer.
