There was a guy from my era of training who claimed to have done such a thing. He also claimed a lot of other stuff as well and I'm pretty sure he ended up chopped at Linton or maybe made it to Valley.
He obviously had some interesting experience outside the military, but was a bit of an Aldridge Prior, so it was hard to pick fact from fiction.
Others may remember his name? Dave ......? Don't think he's still in.
