Paul Shutt, contract manager of the Simplex Grinnell Testing Co., moves out of a hangar full of biodegradable foam after testing the new fire suppression system in the newly constructed Air Force F-35 JSF hangar here Dec. 1. Particularly for fire suppression in areas where petroleum can be present, foam works fastest. It took less than five minutes for the six foam generators to fill the 77,000 square foot hangar with more than three feet of foam. Experts said it could reach the rafters but, for the purpose of completing a series of inspections to certify the new construction ready for use, the test was a success.
