IIRC I had a Big Bertha in '64. I went to a local park on my bike with a Porta-Pad(?), the BB and some other rockets in the basket. I joined the USAF that summer and didn't fly until my first PCS posting. Tyndall AFB, Florida. Discovered Centuri and built a Black Widow. I don't think I ever got the booster to glide on a flight. Built an Estes Gemini Titan and never got both motors to light. An Astron (everything Estes was Astron) Drifter disappeared over the Gulf of Mexico.
