I remember hearing that the main engine compressors have worn out much
faster than had been predicted.  Does anybody know how they are designed ?
More specifically:

	Are they axial or centrifugal ?
	What is their power source ?
	Why are they wearing out so fast ?
	Do they pump the fuel as a liquid or gas ?
	What is their design pressure ?

It has been speculated that a compressor failure could have caused a breach
of the external tank, but I doubt that.

With resolve for the continuation of the shuttle program,
