# Flight 305 path reconstruction (FBI map overlay, DME fixes, placard fall analysis)

Two text files by Robert Nicholson (DME-based airspeed and position; placard free-fall with an 18-knot crosswind) and the FBI flight-path map georeferenced in Google Earth. The underlying radar record is not preserved. Analyses it supports: Monte Carlo drop-zone modelling from jump-time, airspeed and wind uncertainties (compare the site's M-SIG-KINEMATIC and M-SEARCH-PROBMAP methods). Already run:
