Small diversion at NTSB hearing on San Bruno

A security alarm just went off in the NTSB hearing room.  Board chair Deborah Hersman paused the proceedings to explain what's going on and promised that if in fact it had been a fire alarm, she'd let us know.  She then conjured her inner flight attendant, using the two finger gesture to indicate where the emergency exits are located in the room.
