My (bleeping) computer just lost a LONG post that I was making about US use of Spitfires, sort of reverse Lend-Lease. Many of you have seen one in US colors shot down while covering the allied landings at Anzio. The plane is right in the surf.
I read a book by a US pilot who flew US-marked MK V and MK IX Spits over Italy until his unit got Mustangs a year or so later. He liked the Spitfire a lot, but preferred the longer range of the P-51, as it let them make longer strikes into enemy territory.
I don't have time to re-type my comments on the F-5 recon version of the P -38, but it's in suitable books and on the Net.
Rocketdog, thanks for posting this remarkable video. I usually avoid videos here that have little description of the contents. I'm glad that I decided to click on this one.
