Scientific experiments of Atomic Bomb was also primary goal for final order

   One aircraft with photography and video and another with observation recorders accompanied the "Bock's Car" B-29 equipped with the Nagasaki Atomic Bomb. One aircraft was intended to shoot images and videos of atomic bombs. It was the first order of the final order document to install scientific staff for the purpose of observing and recording the power of the atomic bomb. The observation recorder in "Sonde" that was dropped by a parachute just before the Nagasaki atomic bomb dropped was found in Nagasaki city. The Power, explosion pressure, heat temperature, radioactivity, etc. were measured within Sonde. Upon the end of the war, GHQ "general headquarter" immediately collected the Sonde and made the result a top secret material under USA.
