Richard F. Haines, Ph.D.  Copyright 1992   Reports of anomalous
aerial objects (AAO) appearing in the atmosphere continue to be
made by pilots of almost every airline and air force of the
world in addition to private and experimental test pilots. This
paper presents a review of 56 reports of AAO in which
electromagnetic effects (E-M) take place on-board the aircraft
when the phenomenon is located nearby but not before it appeared
or after it had departed. These effects are not related to the
altitude or airspeed of the aircraft. The average duration of
these sightings was 17.5 minutes in the 37 cases in which
duration was noted. There were between one and 40 eye witnesses
(average = 2.71) on the aircraft. Reported E-M effects included
radio interference or total failure, radar contact with and
without simultaneous visual contact, magnetic and/or gyro-
compass deviations, automatic direction finder failure or
interference, engine stopping or interruption, dimming cabin
lights, transponder failure, and military
