When he taxied his DC-3 up to the passenger ramp at Kirtland a few minutes later, several intelligence officers were waiting for him.  He reported that at 9:35P.M. he was on a westerly heading, approaching Las Vegas from the east, when he and his co-pilot saw what they first thought was a “shooting star.”  It was ahead and a little above them.  But, the captain said, it took them only a split second to realize that whatever they saw was too low and had too flat a trajectory to be a meteor.  As they watched, the object seemed to approach their airplane head on, changing color from orange red to green.  As it became bigger and bigger, the captain said, he thought sure it was going to collide with them so he racked the DC-3 up in a tight turn.  As the green ball of fire got abreast of them it began to fall toward the ground, getting dimmer and dimmer until it disappeared.  Just before he swerved the DC-3, the fireball was as big, or bigger, than a full moon.

The intelligence officers asked a few more questions and went back to their office.  More reports, which had been phoned in from all over northern New Mexico, were waiting for them.  By morning a full-fledged investigation was under way.

No matter what these green fireballs were, the military was getting a little edgy.  They might be common meteorites, psychologically enlarged flares, or true UFO’s, but whatever they were they were playing around in one of the most sensitive security areas in the United States.  Within 100 miles of Albuquerque were two installations that were the backbone of the atomic bomb program, Los Alamos and Sandia Base.  Scattered throughout the countryside were other installations vital to the defense of the U.S.:  radar stations, fighter-interceptor bases, and the other mysterious areas that had been blocked off by high chain-link fences.

Since the green fireballs bore some resemblance to meteors or meteorites, the Kirtland intelligence officers called in Dr. Lincoln La Paz.

Dr. La Paz said that he would be glad to help, so the officers explained the strange series of events to him.  True, he said, the description of the fireballs did sound as if they might be meteorites —­except for a few points.  One way to be sure was to try to plot the flight path of the green fireballs the same way he had so successfully plotted the flight path of meteorites in the past.  From this flight path he could determine where they would have hit the earth—­if they were meteorites.  They would search this area, and if they found parts of a meteorite they would have the answer to the green fireball riddle.
