i built a small system that tracks a fixed cohort of business jets (from FAA registry data, matched via ICAO hex) and counts how many are airborne at a given time.
it ingests ADS-B exchange heatmap files (30 min intervals), backfills historical counts, and compares the current value to a baseline for similar times of day/week.
the output is a simple deviation, shown as an "emergency level".
in practice it mostly shows a strong daily cycle, with occasional spikes during holidays, or on april 6th when trump threatened "a whole civilization will die tonight".

where did they go on april 6th btw?
would be nice if you had like a historical record of what happened when your alert level went above 3
