Powerplant
It seems to me that the engine type should be a hybrid of rocket and jet engine. Rockets use a mix of two internal fuels, an actual propellant and an oxidizer. It appears maybe, to save fuel the Vipers' powerplants have intakes to grab oxidizer from the atmosphere when necessary. What's everyone else's opinion? - Panther 20:59, 17 August 2006 (CDT)
