According to their Facebook page, Aerotech will be releasing sparkies soon.
This. Is. Awesome.
For those not familiar with rocketry, sparky motors have titanium mesh (sponge) embedded in the propellant, so as to produce a shower of golden sparks in the exhaust. It's incredibly loud and incredibly cool:

There's actually been a bit of contention lately about sparky G motors which I don't understand; if you want to try to figure it out than I refer you to Dick Stafford. I'm really not sure how AT sparkies fit in, other than it removes some of the argument that they would want to limit sparkies because they didn't make them.
All I know is this: more motor choices = good, possibly flying sparkies with my Aerotech hardware = good, and that I hope to be able to fly sparkies at CATO (no more than G impulse) someday.
