## Aircraft

- Reported make and model: HILLER ACFT UH-12B
- Category: Helicopter

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.
