Yup! Flew Estes and Century rockets. Memorized the "Technical Section" of the Estes catalog. Member of NAR. I've been 6-years-old for 55 years now, so I might be the age of some of the kids you were sponsoring. Lost interest in rockets when I got an R/C system, then flew R/C for years before going back to college at age 26, getting married, having kids... Now I play with drones.
International Rescue uses interceptor drones deployed from Thunderbird 1 and can be controlled by Thunderbird 5 in Orbit ... if need be But they have no props just these super cool blue glowing sorta jet engines
