Condon Committee Theory
In the 1969 Condon Committee UFO report, astronomer William K. Hartmann thought the green fireballs might be explained by lunar material ejected during recent meteor impacts on the Moon's surface . Hartmann's reasoning was that such ejected lunar meteors could account for the abnormally low velocities calculated for the green fireballs by LaPaz of about Earth's escape velocity, that is, much lower than normal meteor velocities. Hartmann further claimed, without explanation or elaboration, that "the predicted characteristics match those of the 'green fireball episode'."
However, this theory would not account for the many other anomalous characteristics of the green fireballs detailed by LaPaz, such as strong confinement to the New Mexico area, lime-green color, low altitude yet absence of sound, absence of smoke trail, and absence of meteorite fragments. Despite the entirely speculative nature of Hartmann's hypothesis, it is sometimes cited as scientific fact: for example, astronomer Carl Sagan presented it as such in his Cosmos television series in 1980.

“I find it profoundly symbolic that I am appearing before a committee of fifteen men who will report to a legislative body of one hundred men because of a decision handed down by a court comprised of nine men—on an issue that affects millions of women.... I have the feeling that if men could get pregnant, we wouldn’t be struggling for this legislation. If men could get pregnant, maternity benefits would be as sacrosanct as the G.I. Bill.”
—Letty Cottin Pogrebin (20th century)
“The theory [before the twentieth century] ... was that all the jobs in the world belonged by right to men, and that only men were by nature entitled to wages. If a woman earned money, outside domestic service, it was because some misfortune had deprived her of masculine protection.”
