Lt. Col. Jennifer Giovannetti (right), 359th Aerospace Medicine Squadron flight commander, adjusts Mr. Alan Nursall’s flight mask Sept. 18, before going on the hypoxia familiarization trainer on Joint Base San Antonio-Randolph, Texas. The hypoxia familiarization trainer is a multiple-airframe simulator that when used in conjunction with a reduced oxygen breathing device, allows aircrew members to recognize and respond to the symptoms of hypoxia due to changes in altitude. Nursall, TELUS World of Science—Edmonton president and chief executive officer, was filming a clip for the television series ‘Daily Planet’, Canadian Discovery Channel’s flagship science magazine.
