- Reported make and model: CONVAIR CV-880
- Category: Airplane
- Engines: turbo jet

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.
