When I was a kid, they were working on the space program at the same factory.
Thanks for the info Amish! Next time I go into BWI I'll look for it. I'm sure my old man flew the one in your picture. Heck, that might even be him in there!!

I may be wrong but I believe the Mars was the biggest operational seaplane ever built. He flew seaplanes out of Whidbey, Alameda and a couple of other places before going to PAX River. I remember him telling me some stories.......whew! He and one of his crew members built a Heathkit DF and used it while flying. Kept them out of some trouble!!
