Détails:
The DC-3 (named 'Saint Kevin') departed Northolt Airport at 17:25 for an IFR flight to Dublin. Last radio contact with the flight was around 19:15 when the flight requested a descent. The request was granted by the Dublin controller, but the clearance was not read back by the DC-3 crew.

PROBABLE CAUSE: "The encountering of a powerful down-current of air on the lee side of Snowdon which forced the aircraft down into an area of very great turbulence were through one or another of several possible causes the pilot or pilots lost control."
