Estes released a nice ready-to-fly rocket a few years ago called the Snitch. Basically, it's a plastic UFO saucer that climbs into the sky, fighting drag the whole way. When the engine burns out, then it flips over and floats back down to earth for a soft landing. It's perfect for night flights, going slow enough to see the bright engine flame yet staying low enough to remain visible (it's day-glo green). We've also staged ours by taping a second motor to the first. Lots of fun, and one of the best Estes releases of recent years.
In the extended entry is a nice photo of three Snitches taking off in formation. Thanks to Steve B. for posting it to the Alt.Binaries.Model.Rockets newsgroup.
