NTSB walked away from this indicated design flaw decades ago after reaching an impasse with the FAA. Impasse for the NTSB but a loss of life for pilots and passengers. NTSB RECOMMENDATIONS TO FAA AND FAA RESPONSES REPORT Data Source: NTSB Recommendations to FAA and FAA Responses Report No: A-83-6 Subject: Letter Date:01/13/1986 Status: CLOSED UNACCEPTABLE ACTION [O] During the period 1975 to 1981, there were 396 engine failure or malfunction accidents in United States general aviation aircraft involving water in the fuel as a cause/factor. These accidents involved, primarily, small, single-engine airplanes and resulted in 72 fatalities, serious injuries to 93 persons, and minor injuries to 127 persons. Engine stoppage because of water in the fuel occurred most often during the takeoff and initial climb phase of flight, and frequently involved older, high-wing Piper airplanes with metal fuel tanks such as the Piper Models J-3, PA-12, PA-18, and PA-22; low-wing agricultural airplanes such as the Piper Pawnee (Model PA-25) and the Cessna Agwagon (Model C-188); and high-wing Cessna airplanes, both old and new, with rubberized bladder-type fuel cells such as Cessna Models C-180, C- 182, C-185, C-206, and C-207. The Safety Board believes that many accidents involving water in the fuel can be prevented and that the FAA should act immediately to address this fuel problem involving general aviation airplanes.

Chalk up two more for prohibition! Tell me if this makes any sense: Substance A causes relaxation, peaceful thoughts and actions, has many medical uses and cannot cause death, but it is strictly forbidden while substance B causes excited, belligerent intoxication, lowers your inhibitions, and often leads to fighting and death but is available in every grocery store. Does that make sense to anyone? Welcome to the land of the free!
