go through the paperwork and you'll see that Mr Pond didn't want the a/c started or much less flown. You're correct they can't do anything until they're paid in full. I met the Pond's once and my impression was that she loved the airplanes very much and they were very active with the museum more so than being the reason for it's very existance.
If you can't fly it, run it at all or even pickle it what the heck would there be a need for ongoing maintence. Their hands seem to be tied by the agreement they signed.

BTW they haven't flown in years.
Over to the experts.
Mr. Pond did ground the airplanes before he died, how ever the museums has always been and will be a flying museum. Every one involved right now has the goal of eventually flying the aircraft. The aircraft donated to the museum, some by Mr. Pond and some by other donors, are able to fly. Mr. Pond set up the trust so that his legacy would be carried on through the warbirds. The airplanes, I ASSUME, were sold to the Museum at a discounted rate because thats the way Mr. Pond wanted it. After all, he was a pretty good business man! All the aircraft will eventually be flown. The tools are integral to being able to not only maintain flyable aircraft but static aircraft as well. After all, we have all seen those airplanes sitting on the road side rotting away. The tools and manuals were always part of the museum. The P-63, Stearman, Cub, C-47, PBY, T-33 and Mustang, belong to the museum, they were all donated.
