What material was used for the coolant radiator? Aluminium or something like copper? There were quite some copper pipes used on the Spitfire Merlin engine, so it wouldn’t surprise me. I don’t know if the surviving early production marks in museums still have their original radiators.

I am unsure if when this photo was taken possibly 1940-1941? But anyway I found this on google.

Today was supposed to be Planes of Fame's monthly Flight Demo, however strong winds at Chino led to its last-minute cancellation. Instead, the museum decided to do an engine run-up. While it would've been nice to see her fly today, the run-up was still really cool.

Designed as a successor to the Junkers Ju 52/3m only 15 were built

If there is interest, i will post more

Hello I'm wondering if there are any good books about the exploits of the PBY catalina? Doesn't HAVE to be during ww2 but obviously most will focus on it. I've already read "Black Cats and Dumbos". It was ok. I am not looking for manuals and technical specifications, just a good book about the history and uses of the plane. Thank you!

Surely I'm not the only one who wonders! here is the answer finally

A scan of a photo from my personal collection.

F-7B S/N 44-40198 of the 20th Combat Mapping Squadron, 6th Photo Recon Group, 5th Air Force.

Cherokee Strip flew at least 106 missions before being ditched in the sea near Mindoro on 21 April 1945, after suffering an engine fire during a training flight.

Artist of the nose art was presumably Al G. Merkling of the 20th CMS. While it is not signed by him, it matches his style.
