Bell 47B (Rick's was an early customer), Travel Air 4000, B-18, Stearmans, BT-13s...great stuff.
I love the open cockpit Vultee (looks a bit like an oversize PT-23), but the captions all seem to call them "BT-19"s, as we know, there is no such thing.

Very cool, thanks Mark! That “war” has been going on for quite some time now. Always amazing to realize that many of todays warbirds survive because someone came up with a civilian-utilitarian use for them.

Here is one that would be fun model diorama-

Hoping the pilot survived that wreck!

The tent in the background looks very cozy.
