That is interesting..
From Jason's Blog:
"… so as the part of the second half in which the bomb went off took place — the replay of the game just suddenly jumped 5 minutes! Five whole minutes of the game was missing! So here’s my question: For those of you who watched the game at home, did the bomb temporarily knock out the TV signal? Or did Fox Southwest deliberately cut out the part of the game when the bomb went off? Interesting."
Interesting indeed..
The bomb went off in the second quarter, just before the halftime. Enough before that they had time to figure out what had happened, and notify the guards at the gates not to issue any pass outs for the half time. (basically return to the game passes)
