From: hallerb on 25 Apr 2010 13:16 Imagine a airliner 3 times the size of the russian androv, or whatever its name is, to loft the 2nd spaceplane to orbit. release altitude 50,000 feet. the airliner could have other uses like a troop transport drop vehicle.

If you are referring to the boosters they are on the external fuel tank, not shuttle. In any event cobb doesn't understand parallel staging. Then again, he's never let reality intrude into his life.

In short, it's an expensive clusterfuck and a double failure to be scrapped. If a plane takes off into the wind the least an orbiter could do is take off from a mountain, taking any advantage available. Denver is mile-high city, why take off from sea level? Fuel is burnt as a function of time, not altitude or velocity, so an electric sled on a ramp providing the initial acceleration would enable a greater payload. |
