Shuttle fleet grounded

The news is bad. I guess NASA overlooked something:

"We had a debris event on the PAL ramp along the LOX field line - below the point where the LH2 ramp begins. Our expectation is that we would not have an unexpected debris event. The PAL ramp is one area we should have reviewed. We knew we would have to remove the PAL ramp. We did not have enough data to be safe and remove it. We had very few problems with it so we decided that it was safe to fly it as is. Clearly, with the event we had, we were wrong." (HT NASA Watch)

Since this is a test flight, back to the drawing board about PAL ramp. All shuttle launches are grounded until future testing said Bill Parsons, Shuttle fleet manager.
