SANTA CLARA, CA (KRON) – A mysterious white foam poured onto the streets of Santa Clara, California Friday.

The foam started coming out of a Signature Flight Support’s hangar on San Jose Airport property at around 11 a.m.

It was caused by the accidental discharge of fire-fighting foam, according to an official with Corporate Communications.

The company does not know how or why it happened. It is likely some sort of mechanical dysfunction.

No damage or injuries have been reported.
