Bill Gates seems to know we are watching the movement of his AC. Today looks like a different flight into Coachella airport with different airspeed and altitude, and, once again, the transponder was turned off just before landing leaving the distinct possibility of an abort and disappear routine. During today's approach the ADS-B was turned off at a slightly different altitude and airspeed, 175ft instead of 75ft and 117kts instead of 121kts.
Since I can't watch him 24 hours per day I am assuming a different flight due to differences.
