"The impact is incredible," Kranz, 85, said. With all the vacated seats, the room reminded him of a shift change when flight controllers would hit the restroom. "So this room is now empty and it's soon going to be filled and all of a sudden, the energy that this room possesses is going to start enveloping the environment here." (AP Photo/Michael Wyke)
