It is really unfortunate that Allen did not set up a trust fund or financial resources that could have allowed the computer museum to fund its ongoing operating budget independently after his death.
It is my understanding that it was 100% dependent on periodic injections of funding authorized by Allen himself, and this was cut off after his sister took control of the finances.
Same for Cinerama.
Is the situation for the airplane museum based in Everett still similar? I haven't heard anything about it in several years.
