Buzz is supposedly going to be on Art Bell tonight, but probably to rebut the nutty crap from Richard Hoagland, who will be the main guest:
http://www.coasttocoastam.com/shows/2006/07/31.html
"Upcoming
"Richard C. Hoagland -Missing Apollo Tapes- enterprisemission
Coast to Coast AM science advisor Richard C. Hoagland will discuss the missing Apollo II video tapes as well as the pending NASA 'Orion' Moon missions.
"11p-11:30p PT: Buzz Aldrin, one of the Apollo astronauts, joins the show."
Thanks.
I wasn't clear on the specific night.
