I attended a 'pre-arranged' ufo sighting (Oahu, 1980) hosted by Wayne Aho, an old timer who'd been in the ufo world since the 50s. He announced it on radio a few days prior.
The 'sighting' amounted to a huge (200+ feet diamater?) circle of white lights in or above low clouds. The lights ramped up slowly as if on a dimmer switch. No sound, other than palm fronds in the wind and surf at beach nearby. After about a half hour the circle slowly moved east, out of sight.
Later I heard he did the same thing around Pacific NW. He was all about The Space Brothers coming to save humanity from itself. I think someone had him on a leash, forced to serve as a barker for their stunts. Years ago he'd been prosecuted for fraud. He was involved with another guy (the mastermind), taking investors $ for constructing a free energy powered spacecraft, with help no doubt from The Brothers.
About 50 people showed up. As we drove up to the old airfield at dusk looking for the entrance, the headlights and interior lights on my old T-Bird blinked off for 5 seconds or so, then back on. A few moments later it happened again. That never happened before, nor since.
