                      The 
                        sighting of three glowing objects by several airline crews 
                        February 24, 1959 is one of the most thoroughly investigated 
                        (and, ironically, one of the most controversial) on record. 
                        The key witness, Capt. Peter W. Killian, was interviewed 
                        by NICAP personnel. A detailed investigation report, including 
                        weather data, air navigation maps, etc., was submitted 
                        to NlCAP by the New York City Affiliate. The Akron UFO 
                        Research Committee co-operated in the investigation, adding 
                        valuable details.

                      The 
                        sighting of three glowing objects by several airline crews 
                        February 24, 1959, is one of the most thoroughly investigated 
                        (and ironically, one of the most controversial) on record.
                      On 
                        February 24, 1959, Captain Peter W. Killian and First 
                        Officer James Dee, American Airlines, were flying a DC-6B 
                        nonstop from Newark to Detroit. It was a clear night, 
                        with stars brightly visible and no moon. At 8:20 P.M. 
                        (EST), the plane was approximately thirteen miles west 
                        of Williamsport, Pennsylvania, flying on a heading of 
                        295 degrees at 8,500 feet. Off the left wingtip, Captain 
                        Killian noticed three bright lights, which he first thought 
                        was the three stars making up the belt of the constellation 
                        Orion. But then he realized that Orion was also visible, 
                        higher overhead. The UFOs were about 15 degrees above 
                        the plane.
                      As 
                        he and Flight Officer (F/O) Dee continued to watch, the 
                        objects pulled ahead of the wingtip. At this point, in 
                        the vicinity of Erie, Pennsylvania, Captain Killian contacted 
                        two other American Airlines planes in the area. One, at 
                        the "Dolphin checkpoint" (over the northern 
                        shore of Lake Erie), saw the objects directly to the south 
                        over Cleveland. The other aircraft, near Sandusky, Ohio, 
                        and heading toward Pittsburgh. spotted the objects a little 
                        to the left of their heading, to the southeast.
                      As 
                        the DC-6B continued west, the UFOs occasionally pulled 
                        ahead and dropped back until they were in their original 
                        position with respect to the left wingtip. Then Captain 
                        Killian began letting down for landing in Detroit, and 
                        the crew no longer had time to watch the objects.
                      During 
                        the forty-five minute observation, the UFOs continuously 
                        changed brightness, flashing "brighter than any 
                        star," and then fading completely. This did not 
                        occur in any apparent pattern. The color fluctuated from 
                        yellow-orange to a brilliant blue-white at their brightest. 
                        The last object in line moved back and forth at times, 
                        independently of the generally western motion of the formation.
                      Visibility 
                        was unlimited. The pilots agreed: "It could not 
                        be any clearer than it was that night above 5,000 feet."
                      When 
                        the plane began letting down for landing, about 9:15 P.M., 
                        Captain Killian and F/O Dee lost sight of the objects. 
                        At 9:30 P.M. in Akron, Ohio, George Popowitch of the UFO 
                        Research Committee received a phone call from a contact 
                        at the Akron airport. A United Airlines plane (Flight 
                        937) had just landed for a fifteen-minute stop and reported 
                        sighting three UFOs which had followed their plane for 
                        thirty minutes. Popowitch had already received nine reports 
                        from local citizens between 9:15 and 9:20 of there UFOs 
                        seen in the area, so he arranged to interview the crew 
                        of the airliner.
                      Captain 
                        A. D. Yates and Engineer L. E. Baney said they had tracked 
                        the object from the vicinity of Lockhaven, Pennsylvania, 
                        to Youngstown, Ohio, between 8:40 and 9:10 P.M. United 
                        Airlines flight 321, also, had discussed the objects by 
                        radio. Captain Yates had seen the UFOs pacing his plane 
                        to the south. But in the vicinity of Warren, Ohio, the 
                        objects passed the aircraft, veered to the right, and 
                        finally disappeared to the northwest.
                      On 
                        May 6, 1959, Major General W. P. Fisher, Air Force Director 
                        of Legislative Liaison, in a letter to Senator Harry Byrd, 
                        stated: "The investigation of this incident revealed 
                        that an Air Force refueling mission, involving a KC-97 
                        and three B-47 aircraft, was flown in the vicinity of 
                        Bradford, Pennsylvania, at the time of the sighting by 
                        Captain Killian. The refueling operation was conducted 
                        at 17,000 feet altitude at approximately 230 knots true 
                        air speed (about 265 mph) for a period of approximately 
                        one hour."
                      THE 
                        NATIONAL INVESTIGATIONS COMMITTEE ON AERIAL PHENOMENA 
                        pointed out several discrepancies in this explanation:
                      (1) 
                        Bradford was to the north of the airliner's flight path; 
                        the UFOs were seen to the south.
                      (2) 
                        Triangulations of the pilots' sighting did not conform 
                        to the altitude and position information given for the 
                        refueling operation.
                      (3) 
                        The American Airlines crews checked with Air Traffic Control 
                        at the time and were told that no three aircraft were 
                        in the area and, after landing, were told that no jet 
                        refueling tankers were in the area.
                      Queried 
                        by the press, Captain Killian said: "If the Air 
                        Force wants to believe that, it can. But I know what a 
                        B-47 looks like and I know what a KC-97 tanker looks like, 
                        and I know what they took like in operation at night. 
                        And thats not what I saw."
                      The 
                        Air Force subsequently released a (unsigned) statement 
                        which they said was made by Captain Killian, saying that 
                        the UFOs might have been a refueling operation and that 
                        he was not aware of what this looked like at night. In 
                        the ensuing controversy, American Airlines instructed 
                        Captain Killian to keep silent. The Air Force officially 
                        concluded that the UFOs were aircraft.
