Luckily, the airplane has its own site (https://thatsallbrother.org/), but even that is fairly limited in its explanation:
”June 5, 1944:
Lead aircraft of the main airborne invasion on the eve of D-Day. Led over 800 aircraft dropping over 13,000 paratroopers behind enemy lines in Normandy.”
https://commemorativeairforce.org/aircraft/165, similarly, is too succinct.
I would have hoped to find out how we know that (scans of logbook, etc, but alas).
Based on what I found, what’s on those sites wouldn’t stay up on Wikipedia. Anybody have better links?
