If this is the same case I read of two or three years back, it
should be noted that not one but three safety interlocks had to fail
simultaneously -- one human, one hardware, one software. The software
glitch has gotten the biggest play in the press, but it was not the
sole cause of the problem.
Yea, the heavens shall open and the NP-complete solution given forth.
ATT executives shall give birth to two-headed operating systems, and
copyrights shall be expunged. The voice of the GNU shall be heard,
but the faithless will be without transcievers.
