## NTSB investigations (1)

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: that the pilot of the other airplane misjudged the distance between the airplanes. The other airplane pilot's diverted attention to the air race is a factor in this accident.
