transfer form earth to orbit not to a trasfer orbit. The solution is that it requires much less fuel and can be done from an airstrip. The notion is to cheap, routine and at will flight to orbit.

[NonZeroSum]

"transfer from earth to orbit" is usually called "launch." Orbit transfer means from one orbit to another.

Anyway, there's no particular reason to think that this would be cheaper than a well-designed rocket. It would certainly be much more complex. We haven't even begun to mature rocketry yet, and can do much better than we currently are without airbreathing.

But can it keep up with the Aurora???
