On second thoughts, my dash to don the dunce's cap (#74) may have been premature ! Of course we
used them, but all the "....Hawk" tribe were as American as Old Glory * (or "motherhood and apple pie").
AFAIK, the Allison
pistons were never fitted to a British aircraft design.
(Note *: if you want to explain our Monarchy to an American, just tell him that it is to us what the "Stars and Stripes" is to him. Most will "get it" at once).
Generally, on the contentious business of "Blue on Blue", the definitive answer was given at the time of the Falklands war by an Army spokesman on the BBC:
"There has never been a war in which this has not happened", and, I venture to add: "And never
will be". (Infinitely regrettable, but true).
