My grandfather is on the right, would love to know more about his career as he died before I was born. Thanks for any info you may have! Great subreddit btw.
There's only one Marine squadron that I know of that flew the Corsair and had the white stripe at the front of the cowling: VMF-114, the "Death Dealers". They stood up at El Toro, and cut their teeth at Peleliu flying ground attack missions.
If it is from VMF-114, I've got a helluva treat for you: how does a 26 minute long home movie of the squadron sound? Perhaps Granddad is in there somewhere.
Edit: Holy crepe, how about THREE HOURS of interviews with a man who flew with VMF-114? That's part one of six.
