Anyone else think that the false alarm the two guys were referring two was the instance when Desmond allowed it to goin to system failure and brought the plane down?
Well, the first time they missed it was when the plane was brought down. However, there was one episode, in the second season I think, where they accidentally let the numbers run down and it showed the heiroglyphics on the screen but then they immediately punched in the numbers and everything was normal again. There was also the time Henry was let out and the system locked locked down, and ruined Locke's leg. The episode with the map. However, this is the second time that it has happened and I guess the guys caught it
