Investigation Summary
The flight was a commercial proving flight ahead of Sabena's planned transatlantic service launch, carrying 37 passengers and 7 crew members. On board were several high-profile passengers, including the family of Sabena's CEO, Gilbert Périer, intended to demonstrate the safety of the route. As the aircraft approached Gander, it encountered dense fog, drizzle, and 60 km/h winds. The pilot, John Ester, attempted to descend below the cloud base to gain visual reference for the airport, but the clouds extended nearly to ground level. The DC-4 struck the forest at 07:42 UTC (02:42 local time), breaking apart and catching fire. While 18 people initially survived the impact, the remote, swampy location made traditional rescue impossible. The United States Coast Guard and Army coordinated a massive effort, flying in Sikorsky HNS-1 and HOS-1 helicopters by transport plane. Rescuers built wooden platforms in the bog to serve as helicopter pads and tent bases. Over several days, the helicopters shuttled survivors to Wolf Lake (also known as Dead Wolf Pond), where they were transferred to life rafts and then to PBY Catalina flying boats for the final leg to Gander Lake and the hospital.
Final Conclusions
The investigation concluded that the probable cause was the pilot's failure to follow appropriate approach procedures for landing in adverse weather conditions. Specifically, the attempt to conduct a visual approach by descending below a cloud base that was at or near ground level led directly to the controlled flight into terrain.
