StrewnLAB Search Area
We have solved a trajectory for this event, from the YouTube videos above, and this data has been run through the StrewnLAB software to predict a search area. We have fair confidence in the trajectory, but the general location of the Winchcombe find was also used to narrow the possibilities. Please download and review the Google Earth files below for detailed maps of the search area.
The weather data below is sourced from weather balloons, and publicly available via NOAA’s Integrated Global Radiosonde Archive (IGRA). This data is downloaded and post-processed by the A computer simulation program, written by Jim Goodall.

The plots have altitude on the y-axis, in kilometers above sea level. The wind speed below 10km has large effect on the drift of meteorites.
