Lt. Col. John Hood, the AMC Field Engineering Officer, outlined the plan in a December 5 memorandum entitled “Technical Approaches to the Problems of UFOs.”  He proposed placing radiation counters over a wide area.  After there had been sufficient anomalous object reports to establish a pattern, the data recorded by these counters would then be compared for time and location with the sightings “to see if any change in the background (radiation) occurs with the presence of sighted objects.”  He also proposed that portable counters be made available which could be taken to the area of a sighting.  Along with the counters he proposed that an aircraft with Geiger counters and also a magnetometer be made available.  The magnetometer would indicate any fluctuations in the local magnetic field associated with sightings.  He also proposed more accurate radars capable of measuring height as well as range and azimuth.  This plan was to begin operating near the end of December.
