I'd forgotten it had a slight upslope. Nope, wasn't me!
I have seen:
When we used to do CSAS BITEs during a hot winch I have seen a set of steps, which were placed at the back of the HAS, picked up by the taileron and subsequently thrashed both the steps, and the taileron, to death. Luckily not my HAS!
A Tornado taxiing out sucking the, un-pinned, HAS door onto the wingtip. I was watching them from my HAS and couldn't do anything to stop it.
