documentedsource_actorContactee & UFO Religion
The movement's physical institutions: the annual Giant Rock Interplanetary Spacecraft Convention (1953-1971/77, peak ~11,000 attendees) and the still-standing Integratron dome (NRHP-listed 2018), an alleged rejuvenation/anti-gravity/time machine.
[DOCUMENTED] Van Tassel's annual Giant Rock convention ran from spring 1953 for ~24 years, drawing most well-known contactees as speakers and up to ~10,000-11,000 attendees (1959 peak); guests landed planes on Giant Rock Airport. [DOCUMENTED] The Integratron is a real 38-ft, 55-ft-diameter, 16-bay all-wood non-ferrous dome in Landers, CA, built from 1954 (main structure ~1959), funded by ~$200,000 in donations (reportedly including Howard Hughes). Added to the National Register of Historic Places in 2018; today run by the Karl sisters as a 'sound bath' wellness venue. [CLAIM] Designed per telepathic Venusian instructions plus Tesla, Georges Lakhovsky and 'Moses' Tabernacle' to recharge human cells for rejuvenation, anti-gravity and time travel - never completed or demonstrated.
