d. Upon examination of the interior of the craft, a compartment exhibiting a possible atomic engine was discovered. At least this is the opinion of Dr. Oppenheimer and Dr. von Karman. A possibility exists that part of the craft itself comprises the propulsion system; thus, allowing the reactor to function as a heat exchanger and permitting the storage of energy into a substance for later use. This may allow the converting of mass into energy, unlike the release of energy of our atomic bombs. The description of the power room is as follows:
(1) A doughnut shaped tube approximately thirty-five feet in diameter, made of what appears to be a plastic material, surrounding a central core. This tube was translucent, approximately one inch thick. The tube appeared to be filled with a clear substance, possibly a heavy water. A large rod, centered inside the tube, was wrapped in a coil of what appears to be of copper material, ran through the circumference of the tube. This may be the reactor control mechanism or a storage battery. There were no moving parts discernible within the (words obscured here).
