i remember that in the late 60's airplanes like the boeing 707 and 720B, maybe also the 727 were equipped with an explosion suppression system manufactured by a company with the name fenwal or similar. The system sensed the onset of an explosion (early flame front) and reacted supposedly fast enough to prevent further progress by triggering a cartridge with a chemical inerting the surrounding air due to its strong affinity to oxygen. the system was definitely much cheaper and lighter than any of the systems discussed now for retrofit in connection with twa 800. This system apparently is no longer used. does anyone know for what reason? was there a basic flaw?
