Only one GA in twenty odd years, but it's quite a GA. When you fly into Kandahar in Afghanistan it's in a darkened RAF Tristar showing no light and with body armour & helmet on. We were very close to the ground as far as we could tell when engines went to full and up we went again.
A few minutes later the Sqn Cdr pilot came on to tell us that ATC (run by the US at the time) hadn't given clearance so he'd gone around. He then added the phrase 'if the Taliban didn't know we were here before they certainly do now....'.
