A bioenvironmental analyst from the 711th Human Performance Wing at Wright-Patterson Air Force Base, Ohio, records data from a piece of equipment inside of a C-130J Super Hercules at Little Rock Air Force Base, Ark., July 24, 2020. Using a custom made pump, analysts from the 711th HPW filled a C-130J with methyl salicylate, a common ingredient in mint candies, and used advanced measurement tools to monitor the concentration of the chemical in the air — effectively gauging how long it takes for the aircraft’s environmental control system to purge the contaminants.
