I've posted a couple of video clips of Ray Goodson's 3" and 5" nozzleless
rockets flights in the early '80s on the AeroTech website. Ray, Chuck Piper
and the other members of RRI were way ahead of their time and the
performances achieved by their rockets have only recently been equaled or
exceeded by contemporary HP and EX fliers.
