No pictures, but they moved Mk 3 Shackletons (the nose wheel variety) into the old T3 hangers at St Mawgan SIDEWAYS on a set of rails: one set for the mainwheels, and lifted the nose wheel with a bigger 'truck' to get the tail in.. Only saw it the once, but the rails were still there a few years ago.
I remember doing that with the Auster 6 tugs of the Bath & Wilts Gliding Club at Keevil in the 1970s. The reason was that the club 'hangar' was a Nissen hut which had to accomodate all the club gliders and the Austers! The only way to get the Austers in was sideways through the 'gable end' of the Nissen hut. I can remember that the three wheels of the Austers were lifted onto dollies but I can't now remember if they were on castors or ran on rails.
Oh, and whilst on the subject didn't BUA cut an appropriate shape out of the frontage of their main Gatwick hangar, above the doors, to accomodate the tails of the VC10s when they were introduced into service in the 1960s?
