Beschrijving:
PanAm Flight 1 was a round-the world flight from Los Angeles (LAX) to New York.
The Boeing 707, "Clipper Caribbean", was on a visual approach to Calcutta (CCU) when it struck a tree and crashed 1128 m short of the runway.
Weather at Calcutta was poor with a 400 ft ceiling and less than two miles visibility in rain.
The crew of "Clipper Caribbean" misunderstood the pressure reported to them by air traffic control. They didn't set the QNH at 993 mb, but instead set the QFE at 29,93. This resulted in a difference of the indicated altitude of 360 feet. The airplane consequently descended below decision height with flaps extended to 50 degrees.
