Sea of foam floods Houston airport hangar

Fire suppression foam was released by accident in a hangar facility next to the Bush Intercontinental Airport in Houston, Texas. The biodegradable foam spilled out of a United Airlines hangar when the fire suppression system went off early Tuesday morning, according to airport officials.

The foam filled the surrounding parking lot and a nearby road, covering several vehicles. No one was inside the building when the incident happened and it did not affect the airport's operations.
