I can't even bare to think of the anguish they must have felt to be able to do nothing but sit in a lawn chair and watch that plane; their labor of love burn so completely down...
Due specifically and only to the idiocy of the PIC (Pilot In Command, Darryl Greenamyer) who began taxi testing and decided to make a run at a takeoff without any pre-checks to make sure all was in order for takeoff. What a freakin' idiot and he should be held entirely responsible for the complete loss of an otherwise airworthy B-29. He should pay for everything that was lost in this fiasco and reimburse all of the people who donated giant amounts of money to completely overhaul all four engines plus props and everything else that needed restoring on this aircraft.
I wouldn't let him ride a rusty tricycle after this.
