What do public safety officials and the general public have a need to know about possible unidentified flying objects (UFOs)? One aspect of the phenomena that may be important involves the possible dangers of "close encounters" with these objects, craft or energy anomalies. According to a 1992 firefighter training book, A Fire Officer's Guide to Disaster Control, the two main hazards are powerful anomalous energy fields and psychological impacts. The authors of the guide, Charles "Chuck" Bahme and William Kramer, primarily focus on conventional concerns and duties of firefighters and fire agencies throughout most of the book.
