I dug up some neat historical records on archive.org pertaining to my namesake, Brendan “Paddy” Finucane, and have posted them below.  I found his own writing published in the Air Forces News Letter, Vol 25 no. 4 of June 1942, which, according to paperlessarchives.com, “was the monthly official service journal of the U.S. Army Air Forces, published by the U.S. Army Air Forces, Air Force Editorial Office.”

Again from paperlessarchives.com:

Articles in the journal chronicle the rapid change in structure of the Air Corps during the first few months of World War II.
Regular content in the journal included instruction from Air Force personnel conveying first hand knowledge gained in combat…
The issues contained messages from top commanders, lifesaving tips, and practical information on aircraft maintenance, gunnery, navigation, and engaging the enemy.

According to Wikipedia, Wing Commander Brendan Finucane was a Second World War Royal Air Force fighter pilot and flying ace, and was the youngest person ever given command of a fighter wing in the history of aerial combat.

Striking to me is the way in which the allied forces shared resources internationally — then Flight Lieutenant Finucane led a famous *Australian* fighter squadron, despite flying for the Royal Air Force.  His rival for top spot among flying aces was a *South African* pilot.  His combat insights were published in the journal of the *US* Army Air Forces.
