Bush: One Wildly Expensive, Covered-Up Failure After Another; This One, Missile Command

No shame, no shame whatsoever with this crew:

A senior Congressional investigator has accused his agency of covering up a scientific fraud among builders of a $26 billion system meant to shield the nation from nuclear attack. The disputed weapon is the centerpiece of the Bush administration's antimissile plan, which is expected to cost more than $250 billion over the next two decades.

The investigator, Subrata Ghoshroy of the Government Accountability Office, led technical analyses of a prototype warhead for the antimissile weapon in an 18-month study, winning awards for his "great care" and "tremendous skill and patience."

Mr. Ghoshroy now says his agency ignored evidence that the two main contractors had doctored data, skewed test results and made false statements in a 2002 report that credited the contractors with revealing the warhead's failings to the government.

The agency strongly denied his accusations, insisting that its antimissile report was impartial and that it was right to exonerate the contractors of a coverup.

The dispute is unusual. Rarely in the 85-year history of the G.A.O., an investigative arm of Congress with a reputation for nonpartisan accuracy, has a dissenter emerged publicly from its ranks.

And Mr. Ghoshroy's assertions raise new questions about the Boeing Company's military arm, the main contractor for the troubled $26 billion system of interceptor rockets now being installed in Alaska and California. The system's "kill vehicles" are to zoom into space and destroy enemy warheads by force of impact.

But years of test failures have thrown the program into disarray, and the military has recently begun to look for a kill vehicle of greater reliability.
