Truly a sad end for any aircraft - to be relegated to a fire dump - but the XB-32?? If you've read anything about the Dominator, from start to finish, that model seemed doomed.
While it may not have measured up to the B-29 - for many reasons - the B-32
is credited with being involved in the very last aerial engagement of WWII - in my humble opinion, more than enough reason to have saved at least one example for posterity.
In any event, there are many more things remaining of the B-32 Dominator than most people realize, aside from several nose/tail Turrets and the famous San Diego WING - which, by the way, is described in that park's handout literature as being from a B-24. I tried to do some photo comparisons of the B-24 & B-32 wing, but came to no definite conclusion as to the San Diego example's true origin. The only way would be to access the inside of the WING and look for a part number: 32 prefix for the Liberator and 33 for the Dominator.
