Two military jets scared residents Wednesday night when they flew dangerously low over downtown San Jose neighborhoods, shaking windows, setting off alarms and creating a deafening noise.

Several residents reported hearing the buzzing through the sky.

"It was very strange," said David Vossbrink, spokesman for San Jose Mineta San Jose International Airport.

Vossbrink said he had no information about why the aircraft was flying low over San Jose, but described the jets as U.S. Navy F-18's. He said they flew over the airfield a few times, but didn't land anywhere.
