An aircraft mechanic wrote to Clifford Carnicom and told his story about working as a maintenance technician at a large airport. After outlining the pecking order of the mechanics and reciprocal agreements among airliners at airports, this mechanic spoke about being asked to work on the waste disposal system on a plane for another airline. After climbing inside the plane, the mechanic noticed that there were additional tanks, pumps, and pipes than normal, and they weren’t attached to the waste disposal system. Confused about this extra equipment, the mechanic looked up the additional equipment on the company computer, but found nothing. Climbing into another plane during inspections, he found another plane with the extra equipment, including what looked like a holding tank. After following some of the piping, the mechanic realized the piping went out to nozzles at the end of the wings. The mechanic had been spotted by management and was confronted about doing this investigation by managers and union reps. He was accused of falsifying paperwork for a job he did, and later received an anonymous phone call at home with the caller saying ‘Now you know what happens to mechanics who poke around in things they shouldn’t.” After finding the Carnicom web site, the mechanic wrote this letter to Clifford Carnicom attesting to the fact that the airlines are indeed spraying from these airplanes.
