"Gyrotron is unique, a $3,000,000 ride of the future suggesting outer space and the unknown. It puts the passenger into "orbit," dumps him into a hissing, spitting volcano to be swallowed by a huge monster living within in it. It's the fantasy of another world." -- quoted from "Bill Bantey's Expo 67" book, a publication of the Gazette Printing Company (Limited), Montreal, April, 1967.
