Newsreview, published by the Air Force Systems Command, told of a special "bake job" done for NASA by Patrick Air Force Base, Fla., in its Civil Engineering Squadron's fabrication-branch shop. Ovens there, normally used to harden, soften, or anneal metals, were large enough to treat 75 to 80 thermal tiles from Shuttle orbiter Columbia damaged by a nitrogen tetroxide spill. The heat treatment at 1,100-1,400°F took about 16 hours to burn off contaminant and bonding material. Checking for toxic vapors caused by the heat disclosed none. (AFSC Newsreview, Nov 27/81, 8)
