I'd recommend watching ebay for that one.
The original Astron (gliding) Estes one comes up more often, as does the bagged Estes one.
Unless someone here has one they are looking to sell, you are going to wait a while on this one.
They don't pop up often.

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
