In the world-wide amateur rocketry realm, are any other SOLID
oxidizers in use or development aside from KNO3, KP, and AP?
Have successes been possible with AN as majority mass of an oxidizer
blend (>51%)?
Ditto, with AN as an oxidizer at >10% mass?
Nothing happening with guanidine or other nitrates? Other perchlorates
(or chlorates)?
[Catching up on the news, and states of our art.]
