According to Markey, the drill was designed to prepare stadium staff and police for a terrorist attack.
The drill used a concert scenario where a biological agent is released into the stadium before a rock concert, staff members are dead, concertgoers are waiting at the ticket counters.
During the emergency drill, local police, the FBI, a bomb squad, and ambulances massed in parking lots. Helicopters hovered above the football field to get photographs.
While the stadium does emergency plans and dry runs of emergency situations, this was the first time the FBI was included in the planning effort.
