On 4 March 2022, a Sikorsky S92A touching down on the designated landing site at a Plymouth hospital to deliver a recovered casualty subjected several people in an adjacent car park to significant downwash. Two were blown over sustaining serious injuries with one dying later the same day. Hospital management was found to have failed to effectively assess the risks of landing site operation and its communications with the operator to ensure safe site use. The landing site was not being operated in accordance with guidance applicable to more recently opened sites nor was it required to be.
