The only actual hit ever suffered by a RAAF Hercules from ground fire (at least in my day) was a .303 hole in the elevator of an A (or was it an E?) model doing circuits at Laverton.
The (today he'd be called a) 'terrorist' was a RAAF sergeant bluntie who objected to the noise interferring with his watching of the early 70's equivalent of 'Days of our Drearies', whatever that was.
Quite rightly he suffered the full force of the law, but you had to give him some credit for getting his lead angle almost right - a number of other people a rather long way north of Laverton and armed with weapons a bit more modern than the three-oh had the odd go at the Hercs over the years and never once scored a hit.
