Thomas G. Kaye, Robert Nicholson, Cooper Research Team, n.d.. citizensleuths.com.
Reconstructs the flight from the FBI transcripts (two DME fixes at 19:40 and 20:22, Victor 23, the towns named), overlays the FBI flight-path map in Google Earth, estimates airspeed and wind, uses the placard find to bound the aircraft's position, and reports a telephone interview with the air traffic controller. Links two text files of Nicholson's calculations.
