During the '82 South Atlantic Games an RN Lynx on picket at altitude and well away from the Fleet was attacked by a couple of Argie Miracles - apparently he knew he was under attack because of the cracking sound of the cannon shells going by - he rolled the Lynx on its back and dove for the deck - he credited his escape on the manoeuvrability of the helo and the fact that the Argie pilots thought that it was probably all too easy and did not consider a co-ordinated pairs attack.
I was involved in some semi-official 1 Huey v 2 Macchi years ago and even that venerable old machine could generally hold its own.
If a modern helo knows you are about he will more than likely be able to well and truly out manoeuvre you and the next thing you know - "bingo".
