UFO Hunters Kokomo

"UFO Hunters" Science Producer John Tindall created a special cannon that duplicated the "N" wave signature of a sonic boom. The device was 28 feet in length with a 12' and 3' steel combustion chambers using mixtures of propane and oxygen. The chambers were isolated and were fueled with separate O2 and propane manifolds and also detonated at slightly (milliseconds) different times.
