                      A 
                        domed disc near cargo airliner, confirmed by the airplane's 
                        airborne radar. The object was disc-shaped with a transparent 
                        dome on top, and a silvery, highly polished surface. The 
                        object reacted to the sweep of the plane's radar. Pilots 
                        from the airliner saw two or three shadowy entities moving 
                        around inside the object.

                      Domed 
                        Disc Near Airliner, Confirmed By Radar.
                      An 
                        airline DC-8 cargo flight was en route from St. Louis 
                        to Dallas on February 14, 1973, at about 2:30 a.m. At 
                        a point near McAlester, Oklahoma, the co-pilot noticed 
                        what he first thought was another aircraft just below 
                        the leading edge of the right wing about 5,000 feet (1,500 
                        meters) away. The object was on the same course and speed, 
                        keeping a constant position. Only its steady amber light 
                        seemed unconventional.
                      Suddenly, 
                        the object rose straight up like an elevator, made a sharp 
                        turn and approached the plane, taking up a position about 
                        300 yards (270 meters) away and slightly above them. It 
                        was disc-shaped with a transparent dome on top, its silvery, 
                        highly polished surface reflecting the moonlight. Besides 
                        some stubby protrusions, no other features were visible.
                      The 
                        captain switched on the weather radar and it confirmed 
                        that something real and solid was there. When the radar 
                        beam hit its surface, the object reacted immediately, 
                        ascending straight up, then moving sideways over the DC-8 
                        and briefly out of sight. The object reappeared quickly, 
                        descending straight down and taking up a new position 
                        just below the leading edge of their left wing. It then 
                        dropped below and behind the plane, abruptly reappearing 
                        only about 300 feet (90 meters) below them.
                      Looking 
                        down into the dimly-lit dome, the pilots saw two or three 
                        shadowy entities moving around. The object then darted 
                        out in front, performed various oscillatory motions and 
                        another sharp (non-inertial) turn before speeding out 
                        of sight. It disappeared off the radar scope at a distance 
                        of 50 miles (80 km).
