If shot down, this Chinook would hardly be the first; one full of U.S. Special Forces guys, on a mission to recover the survivor of an ambushed S.F. team, took an RPG straight into the open tail door, killing all on board.
The sole survivor of the team they went out to rescue was picked up by National Guard reservists in a very hairy operation, repeated by another flight by them the next day to bring his comrades' bodies back, again in a very hostile situation.
As in the plain daft thinking behind the Tornado & JP233, no-one yet seems to have come up with a defence against simple artillery - " Shields up, Spock ! "
