Why a Sacramento suburb looks like America's laser-strike capital

Since 2021 the FAA has logged 54,722 reports of lasers pointed at aircraft. Sort them by city and the list starts sanely — San Diego, Houston, Phoenix — except for the line at the very top: Mather, California, an unincorporated Sacramento suburb of a few thousand people, with 1,974 reports.

Mather is not a hotbed of laser crime. Mather is where Northern California TRACON (NCT) sits — the radar facility that works arrivals and departures for the entire Bay Area and Sacramento Valley. When a crew reports a laser to NorCal Approach, the FAA record carries the reporting facility's location. Thousands of strikes that happened over Oakland, San Jose or Sacramento are filed, on paper, in Mather.

The lesson generalizes: government incident datasets encode their own reporting plumbing. Any per-city ranking of FAA laser data is really a mixed ranking of geography and bureaucracy — and the number one "city" is the clearest tell. Filter the facility codes out and the real geography emerges: Southern California, Texas and Arizona metros lead, roughly tracking population and clear-sky nights.
