The NIDS website has linked to an extremely interesting report by the National Aviation Reporting Center on Anomalous Phenomena, titled “A Preliminary Study of Sixty Four Pilot Sighting Reports Involving Alleged Electro-Magnetic Effects on Aircraft Systems” (May 2001). The paper is not all smooth reading, with its purpose being to outline statistical occurrences of anomalous effects on aircraft, but the conclusions are definitely worth a discussion. Not to mention there is some excellent material in the case reports quoted in the second half of the essay.
