Here is photo of some wealthy man who loaded relief aid supplies into his privately owned WW2 military plane and he even loaded relief aid supplies into his bomb bay space for his flight to Houston that was hit and flooded by hurricane!!! Look at guy loading up supplies into bomb bay.
FYI, Devil Dog isn't owned by some "weathly man." It's owned by the members of the Commemorative Air Force who work hard and keep it and over 100 other Warbirds flying across the United States and France. I'd love to tell the primary pilot of Devil Dog that she's now a "wealthy man" though. She'd get one helluva kick out of it.
I suspect other CAF aircraft will be involved as well, but they're all busy getting to Midland for AirSho 2017 so they can raise a bunch of money for relief efforts too.
