1969912 0 #1 January 4, 2007 One of the firms pursuing low-cost space flight has posted video of a demo launch on their website. Their propellant combo of choice for actual flight is rumored (they're pretty secretive) to be Hydrogen Peroxide/Kerosene (RP-1), but the demo video shows no flame from the nozzles. It would seem that H2O2/RP-1 would generate a visible flame. I'm wondering if the demo was actually done with a H2O2/Catalyst motor, and not the bi-propellant. Any opinions?
