December 12, 1212 - Mark Kelly Olson, the 10-year-old son of Aerospace Testing Alliance operations controller Mark Olson, dons a customized fire helmet he received from the Arnold Air Force Base Fire Department, showing his honorary title as a “true hero,” at Vanderbilt Hospital in Nashville, Tenn.

Arnold Engineering Development Complex Fire Department Chief Daryle Lopes and Fire Chief Kip Luttrell spearheaded the effort to rally moral support for Mark since learning that he had been diagnosed with very high risk acute lymphocytic leukemia earlier in the year.
