VIDEO: Cleanup is expected to last through Thursday night into Friday morning after fire suppression foam was "inadvertently" released at about 5:30 a.m. at one of the United Airlines hangars that dot a public service road at Bush Intercontinental Airport.
It happened just off Wright Road, in a hangar adjacent to the flight attendant training facility. Large amounts of fire suppression foam seeped onto nearby parking lots, around fences, posts, over cars, and eventually on a portion of the public Wright Road. It wasn't long before the Houston Fire Department was called in to assist.
"Because of its high expansion properties, it was as high as 30 feet," Houston Assistant Fire Chief Mike Mire, one of several HFD officials on the scene, said.
Work crews spent hours spraying the foam with a defoaming agent.
