Photographs and video of the scene shows numerous Black Hawks buried in the white, fluffy foam — both in and out of the hangar. Each helicopter is 65 feet long and about 10 feet tall at its highest point, the tail rotor.
Moss said Tuesday that the hangar had at least six Black Hawks in it when the fire suppression system deployed, and others outside also were affected by the foam. The aircraft weren’t damaged, and six of the 10 affected have been cleared to fly again.
“We were surprised by the accidental activation of the system, but I think it was educational to those working on those aircraft every day to see how effectively that foam deploys,” Moss said.
Video of the hangar published by KOTV News 6 shows it rapidly filling. It took the contractor about three hours to clean up the mess, Moss said.
