> The dark flight trajectory of a meteoroid is significantly affected by the atmospheric winds, especially by the jet stream. As a result, the meteorite fall position can be shifted by up to several kilometers compared to a scenario with no winds.
That network is mostly interested in where it falls, not where it came from. A few degrees for finding an origin is a huge variation.
Planetary scientists are motivated to physically examine freshly fallen near pristine samples, yes. They are also keenly interested in origins, intra or extra solar system, relationships to known showers et al.
The less public precursors were and still have an interest in both projected targets and sources.
