AUTOBAHN BRIDGES
In the late 70's and early 80's as a Sqn pilot, Flt Comd and Sqn Comd, flight under autobahn bridges during tactical exercises was endorsed and also practised during training. Never did it at night, this was pre NVG. Surely this falls into the same bracket as flight under wires - now I have done that on NVG and there is NVG Video of this taking place during a trial in '92.
Bet there's a few other Pruners out there who can admit to both wires and autobahn bridges.
