I live less than ten miles from them and they seldom make the news,
let alone substantial details. What little has come out recently
seems to suggest they've made additional flights, but probably
not with the vehicle that'll have a serious propulsion system
(something more than peroxide alone for propellent). Not a clue on
their propulsion systems development status that I've heard of.

Frustrating...


They are going to have a hard time getting the performance they want
with simple H2O2 decomposition and no fuel burning with the released oxygen.
You would think they would add either alcohol or kerosene to the mix;
the latter is quite a good propellant combo, as Black Arrow showed.
