Dear All Gary Fenical of Laird Technologies told me about an interesting new report from the Nasa Aviation Safety Reporting System.
You can download the report from: http://asrs.arc.nasa.gov/report_sets/ped.pdf This May 2002 report concerns problems with Personal Electronic Devices (PEDs) on board civilian aircraft, although not all of them are about interference. All the very best! Keith Armstrong www.cherryclough.com
