NBC News anchor and former volunteer firefighter Brian Williams doesn't expect to hear alarms during his day job.
He did Tuesday night, when an audible fire alarm from a floor below the "Nightly News" studio in New York repeatedly interrupted the newscast.
Spokeswoman Erika Masonhall said Wednesday that it was a drill, but that technicians couldn't immediately turn off studio loudspeakers. "Nightly News" moved into a new studio a month ago.
Alarms went off twice as Williams read a story about American Airlines. He flashed a bemused smile the second time and said, "We should remind our viewers that there's no danger to us."
After the problem was fixed, Williams redid the broadcast for non-Eastern time zones.
