I should have said I don’t think they are planing to develop a rocket engine based on the press release I’ve read. But then, it also doesn’t sound like they even have a concept design yet, so maybe they will just end up with a rocket engine if they actually want to go hypersonic.

So is propane, but not when it's used in a BBQ.
