N930TH: a ground-speed report of 1,005.6 kn

Tail N930THAircraft type not recordedCallsign HBAL837

Tail/type: current database matches; historical assignments unverified.

A saved ground-speed report reads 1,005.6 knots. The observation preserves that unusual reported value and the available surrounding readings; it does not establish the aircraft’s actual performance.

Evidence and limitations

Aircraft metadata is a current database match; historical assignment is not independently verified.

An outlying report alone does not establish an aircraft's performance or the cause of a data error.

15 archived ground-speed readings around the selected value. Each dot is a saved report; lines stop at gaps over 45 seconds, source changes and rejected readings. Archive timestamps do not establish exact message freshness. The peak is an unconfirmed reported value, not verified aircraft performance.
