On 13 March 2014, an AgustaWestland AW139 helicopter of Haughey Air crashed shortly after taking off at night in fog from Gillingham, Norfolk, United Kingdom, killing all four people on board. Among the victims was Edward Haughey, Baron Ballyedmond. The subsequent investigation concluded that the flight crew may have been subject to somatogravic illusion due to the lack of external visual cues, inducing them to manoeuvre the aircraft into the ground instead of climbing away.
