Golden Gate Bridge fog horn malfunctions overnight

One of the three fog horns on the Golden Gate Bridge got stuck.

From 2 a.m. to 3 a.m. the horn was blaring in one continuous tone. People were calling 911; some claiming aliens were attacking the city.

Workers finally disconnected all three horns on the bridge. We don't yet know why the horn got stuck. The horns are 70-years-old.
