## NTSB investigations (4)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: The failure of the glider towing "weak link," for undetermined reasons, at an inadequate altitude to effect a normal landing, resulting in a hard landing.
