rocketA fascinating article on the pros and cons of air-breathing spacecraft vs. rockets for orbital launch at Short Sharp Science:

Trying to build a spaceship by making airplanes fly faster and higher is like trying to build an airplane by making locomotives faster and lighter – with a lot of effort, perhaps you could get something that more or less works, but it really isn’t the right way to proceed. The problems are fundamentally different, and so are the best solutions.
