On three runs a spray of propylene oxide was detonated inside a tactical fog cloud. The FAE did not ignite the fog oil cloud nor was any clearance evinced as judged by visual observation and camera and television recordings. Transmissometers with lines-of-sight through the clouds operated in the visible and three infrared bands. Immediately after detonation, the transmittance was reduced in all four spectra bands. The reduction in transmittance was probably a result of dust lofted by the FAE. It was concluded that tactical fog oil clouds are very probably too lean to ignite. There was no difficulty in detonating a fuel-air cloud in the covering fog oil cloud. 收起
