Philippine Air Lines Flight 785
On June 29, 1966, the flight crashed on the slopes of Mount Rabangan near Sablayan, on the second leg of a Manila-Mamburao-San Jose route that originated from Manila.The aircraft was a Douglas DC-3 manufactured in the United States and had its first flight in 1944, registered as 43-16107, before being delivered to Philippine Air Lines and re-registered as PI-C17.The dispatcher stated that he gave a weather briefing to the crew that continuous heavy rain was expected throughout the segment of the flight.He was unsure of the Flight 785's time of departure and arrival at Mamburao until another aircraft relayed a confirmation message, as it was standard procedure.[6] The wreckage and two survivors were found in the afternoon of July 1, 1966 in a ravine at the northern slope of Mount Rabangan, in an altitude of 2,300 feet (700 m).The entire fuselage except for the outer section of the wings and the tail surfaces were damaged by impact and the ensuing fire.The cause was determined to be a misjudgement of the terrain clearance resulting in the collision with trees and the mountainous slope, aggravated by severe turbulence and strong winds over the crash site.
