I agree with whoever said in the article that these things happen. I mean, this was the first time something like this was built. It's only natural to expect that they won't get it right the first time around. Hell, I wouldn't be surprised if several of these glitches occurred before they actually get it to work properly.
On the flip side, though, with so much money pumped into this thing, it should not only work, but bring an end to world's poverty and cure AIDS. :P
