The aircr:ft had to be positioned within a very close ptaeiis on position in space relative to the device so that the fixed waneEacounted on the aircraft could photograph the detonation. As the normal airborne radar would not scan above the aircraft and since the target was a free meving, body in the upper air currents, a special installation of an E-l radar set with an upward field of scan was made on these aircraft and a beacon installed in the equipment carried by the balloon.
