On July 3, 1947, a US Army C-54, carrying a crew of six and flying on a routine flight from Bermuda to Morrison Army Air Field, Palm Beach, disappeared somewhere between Bermuda and Palm Beach, its last position being about 100 miles off Bermuda. An immediate, intensive air-sea search by Army, Navy and Coastguard units covered over 100,000 square miles of sea, although (except for some seat [covers?] and an oxygen bottle, not identified as equipment from the lost plane) no wreckage or oil slick was sighted.
As further disappearances occurred, a somewhat alarming coincidental feature was noted, ie that the majority of the incidents within the triangle area seemed to take place within the [Peak Tounat and Hotel area?] from November through February. Even more startling was the realization that many of the losses have occurred within a few weeks before or after Christmas.
