Products: evtol, air-taxi. Risk band: Elevated RobotRisk index 19.5/100 (incidents/exposure, time-weighted) · 96th percentile of 171 drones evtol companies.
The record consists of one entry: the VX4 prototype eVTOL aircraft crashed during an uncrewed flight test in August 2023, coded at severity 4, the highest severity level in this dataset. The uncrewed designation limits the event to a hardware-loss classification rather than a casualty incident. Vertical Aerospace's index (19.7) and percentile (96.5, elevated band) place it well above most category peers, consistent with a single high-severity test-flight failure. The record is a single press-reported flight-test event, not a pattern of recurring failures.
