Attribution reflects public context; registration records show registrants, not passengers.

Built from JetSweep’s retained FAA registry snapshots, sourced from FAA Registry N434DF (snapshot Sep 24, 2026). Dates shown are FAA recording and snapshot dates — the day a filing was indexed or a difference was first observed, not necessarily the day the underlying transaction happened. Part 135 rows come from dated workbook retrievals and bound a listing, never date it. We track the aircraft, not who is aboard.
