Many moons ago I was at what is now a former Buccaneer base in Suffolk when a 10 turned left at the end of the landing roll at the 27 threshold instead of right and ended up at the HAS site gates. VAS had no tow bar and there was not one on the aircraft. The aircraft had to reverse about a hundred yards before being able to turn round in what I think was probably a former V bomber dispersal narrowly missing a lighting trolley in the process. This is the one and only time I have ever seen a 10 reverse under its own power. After getting the steps in when the aircraft finaly got to the main ASP we were greeted with a tray of Tea & stickies!
Air Canada regularly use to reverse thrust their 727's off the stands at Calgary but that was also a long time ago.
