Considering about 800 million passengers per year in US, that's 800 million extra hours of awake human that the additional hour to handle security requirements suck up. Considering a 79 year lifespan per human (totaling 461360 awake hours), that's around 1734 human lives wasted per year in US. 9/11 only killed 2996 people, of average age 40, so roughtly could be said that the extra hour of airport security in US costs a 9/11 every year. (I'll admit, maybe people having a friendly chat in the secutiry line or otherwise enjoy the extra time in the airport terminal, so not exactly apples-to-apples comparison).
