A computer program was written to determine the trajectory of supersonic aircraft from the arrival times of the sonic boom. The program was used to estimate the flight path, velocity and height of eight space shuttle landings and one flight of the SR-71 Blackbird plane, which were recorded on the southern California seismic network during 1989 and 1990. It was found that the direction of the flight path can be resolved fairly accurately, while there is much more uncertainty in the velocity and height estimates.
