I discovered a sound that leaks your exact location (and it's everywhere) - YouTube

Simon Willison's link-blog post of 3 November 2026 points to a YouTube video by Colsto on locating where a video was recorded from faint aircraft noise in its soundtrack. The method extracts Doppler curves of passing planes, then matches speed, distance and gaps between flights against ADS-B flight data. The post is a short pointer and gives no step-by-step detail.

TL;DR Link to a Colsto video that geolocates footage by matching background aircraft Doppler curves to ADS-B flight data.
