First Solos
When I was in the RAF, one of the flying tours I did was on the Shackleton. It was a Mark 2 converted for AEW, but after the fifth flight we (two new co-pilots) were sent off by ourselves to do five circuits each, the last of which was asymmetric. In the Shackleton that meant actually shutting the engine down as opposed to setting zero thrust as is done in the civilian training world. Somebody must have had a lot of faith to send two guys with not much more than six or seven hours each to practice landing a 70000 pound taildragger by ourselves.
Although perhaps not quite in the same league, the Buccaneer never did have a two stick variant, so evey pilot who flew it did a first solo on his first ever flight in the front seat of the aircraft.
