Our Past-President died when his Cessna 172 flew into the Irish Sea on 25 November 2019. He was the sole occupant.
The Senior Coroner for north-west Wales said that an “open verdict” would be recorded, due to insufficient evidence that could provide a detailed reason for Prof Last's death.
The summary of the Air Accidents Investigation Branch (AAIB) report, published on 29 October 2020, states:
“The aircraft was on a local flight when it descended into the sea, killing the pilot. No definitive cause for the accident could be found. There was no evidence of a structural failure leading to the accident and a trial to replicate the final flight profile discounted a full or partial engine failure. The trial concluded that it was likely the aircraft required an input on the controls in order to enter and maintain the recorded final descent path. The pilot had recently been unwell but there was no evidence of medical incapacitation, although this could not be dismissed as a possible cause.”
