Easy there, canadiancitizen. Notice the title of this thread?
US Navy Spitfires D-Day It isn't bashing anyone else, or glorifying one particular nation and not giving any credit to anyone else. Its like Za put it - learning something new everyday on the Forums. I too was unaware that the US flew Spitfires either.
All of us here hold every nationality and person that served in WWII with great respect (minus a few bad apples who get banned by
der PanzerPenguin
) so need need to get upset over this.
Your information does explain one thing to me - my family originates from England, and my grandfather was a Bombardier flying for the RAF. For some reason, his logbook is RCAF (not sure why, he never lived in Canada) though I do know his wife had several Canadian Cousins - 3 of whom were RCAF Fight Pilots and all shot down within a month of each other.
EDIT: While writing this, JCF posted a response along the same lines as this.
