On September 18, 1947, the committee was surprised and alarmed by a report of reconnaissance. An Air Force plane out of Bermuda flew into a big hurricane which was moving west-northwest to the south of Bermuda and, after a rough time in the outer parts of the storm, finally found its way into the eye. Immediately they saw a Navy Privateer flying around in the center, also on reconnaissance, and they got right out of the eye and returned to base. There they made an official protest that there is not sufficient room for two planes in the center of the same hurricane. New instructions for co-ordination were issued immediately to all concerned. It is not surprising that this has happened on at least two other occasions, once with two Air Force planes and on another occasion with a commercial airliner. In 1953 there was another bad accident, but not directly in a hurricane area. It resulted from a moderate hurricane named Dolly, which came from the vicinity of Puerto Rico on September 8 and moved toward Bermuda with increasing intensity. On the tenth, aircraft in the center estimated the highest winds at more than one hundred miles an hour, but on the eleventh it weakened and passed directly over Bermuda. There were strong gales at Bermuda, although the storm was diminishing in force so fast that no serious damage resulted. On the tenth an Air Force plane from Bermuda flew into the hurricane. A Weather Bureau research man, Robert Simpson, went along to follow up on some studies he was making of the circulation at high levels in tropical storms. He reported: “Dolly was an immature storm with most of the cloudiness concentrated in the northern sector. On the south and west sides, clouds rose only to around seven or eight thousand feet near the eye, except along the spiral rain bands which encircled the eye. The plane first investigated conditions at one thousand five hundred feet in the eye, where it was observed that there was a huge mound of cloud near the center with a moat or cloudless area which encircled this central cloud and separated it from the walls of the eye.”
