Sea of foam cascades out of airport hangar
A bobbing sea of white foam several feet deep engulfed an airport in California, covering cars and blocking off nearby streets.
Officials said the foam had spewed out of a large hangar at Mineta San Jose International Airport, where it is used as a fire retardant. The chemical had discharged accidentally from a storage unit inside the hanger, and quickly spread.
The flow left the nearby area looking like it had been hit by an unexpected heavy snowfall, with a wide area left under the white blanket.
Residents were urged to stay out of the foam, though video from the scene showed one man on a bicycle emerging from the fluffy mass. Authorities said the chemical was not dangerous.
The foam disappeared within a few hours.
