On 21 April 1948, while on approach to Renfrew, a Vickers VC.1 Viking, registration G-AIVE, crashed into Irish Law Mountain in North Ayrshire, Scotland.

No one died in the accident, but 13 of the 20 passengers and crew were injured, and the aircraft was damaged beyond repair.

[1] After a one-hour flight, air traffic control at Glasgow-Renfrew cleared it for a standard beam approach into the airport.

The last radio contact was at 20:01, when the crew requested confirmation that the outer marker was operative.

[2] Some remnants of G-AIVE remain on the hill at Irish Law Mountain, including the engines, landing gear, and parts of the left and right wings.
