Having done a bit of fast jet v. my Puma, I wasn't too bothered about them. It was the thought of the Frogfoot that did.
Mind you, the USAF did manage to shoot down a couple of Blackhawk with their F-15s a couple of decades ago, killing all 26 persons on board.
But they were supposed to be on the same side, so I wouldn't have thought the Blackhawk pilots were expecting the threat from above.
