Foam Accident in a Hangar. Again.

Fire-retardant foam accidentally filled an empty hangar in Allegheny County Airport, Pennsylvania.

"Our foam system appears to have malfunctioned," said Craig McDivett of West Mifflin Emergency Management. "High expansion foam is really nothing more than glorified dish soap.”

The foam kept coming and coming.

Officials estimate a little less than a million cubic feet of foam filled up 150 x 150 foot Corporate Air hangar.
