That was a neat shoot! The Yank Bird Gunners were attached "Under Command" and I was tasked to be the RSO. They did an amazing demo of bird gunnery and then showed the effects of a Vulcan on tanks. A twenty second burst hammered into an old Agony Wagon (Centurion) about 1000 metres down range and you could see the rounds hammering into the turret armour and ricocheting all over the place... after about 12-14 seconds the armour was white hot and just sort of melted inwards allowing the last hundred or so rounds into the turret to cause major disruption of the colloidal intelligences that would have been inside!
Damn near talked them out of the weapon system too... didn't have enough Scotch on hand!!!
Ed, any chance I can get a copy with the photo credit at the bottom?
