The airline reported this was an unapproved overflight of the town the captain grew up in during the captain's retirement flight. The airline is looking into the very serious matter internally.
Residents reported they were puzzled by a very low flying aircraft.
ADS-B data transmitted by the aircraft show, the aircraft descended to 1375 feet on standard pressure setting (1013.25 QNH) while actual ambient pressure was 1003 QNH. Therefore the transponder altitude (1375 feet) was indicating about 300 feet above actual altitude.
