There is also another explanation, all the cited sighting of green fireballs prior to 1960 took place near a national lab, or research lab. The one below in Los Alamos, one in Albuquerque where Sandia National Lab is located and a some in Alamogordo, which is next to Holloman AFB and White Sands Missile Range. Is it possible that lasers were really invented long before the public was made aware of them? Really they were invented years before Theodore Maiman patented his ruby laser, but for some reason this was top secret and so Maiman was just allowed to patent it and take credit for inventing the laser?
Just a thought.
Another thing I found interesting was the reference in the article to the thought control office. According to the site I got the article from, the writer is actually being sarcastic and referring to the Atomic Energy Commission. :-)
Los Alamos, New Mexico, Skyliner - 29 Feb, 1949
Flying Green Lights Alert Constabulary
By THE OBSERVER
Shades of the flying saucers!
Los Alamos now has flying green lights.
These will 'o wisps seen generally about 2 a. m., have alerted the local constabulary and their presence is being talked about in Santa Fe bars.
But local wheels deny any official knowledge of the sky phenomena. Each one passes the buck to another.
A call to El Paso, Tex., brought official denial from D. K. Brown, head of the Federal Bureau of Investigation district that embraces Los Alamos, that his agency had not been called to deal with the matter.
At the information or thought-control office officials indicated that they knew about the recurring green flame in the sky but indicated that it wouldn't be wise to write about it.
Capt. Carroll Tyler, project manager, said simply that all he knew about the lights was rumor -- the same rumors that everyone is hearing.
Call the Army
At the thought-control office the general reaction was that the matter was out of AEC jurisdiction and the best way to find out what was going on was to call Kirtland Field.
A call to Kirtland showed that an Army captain who asked that his name not be used because he didn't know anything, didn't know anything. He was eager to learn, though.
Official reaction was the same on the Hill except for the atmosphere of secrecy that has been thrown about a matter discussed in every saloon and drawing room from here to Santa Fe.
There was even no speculation. Could these be visitors from Mars or from the Russias [sic]? No answer.
But enough competent observers had told this observer that there was indeed something in the wine.
Shott [sic] Down Venus
And something much more tangible than the time last summer when one of the local security officers ordered out tanks and jet planes from Kirtland Field to shoot down a light low on the horizon that happened to be Venus, a well-known planet.
The jet pilots, trigger fingers ready, were disgusted at that alarm. Maybe that's why they're now querying the green lights.
Have you seen a green light lately?
