I had a conversation with one of the volunteers last year, but have forgotten his name unfortunately. Doh !
United withdrew financial support in 2001 which is not entirely surprising given what else was going on. His version was that the 6 would be donated to a museum. I thought it was the putative one at Mojave, but it could have been Pima. Definitely not to a scrapyard though. Situation might have changed of course. Is she airworthy ?
(N578AS for the spotters, never flew for United but is ex-US Navy.)
