In a 1945 publication of the Albuquerque Journal, a journalist reported that Georgia Green, a blind 18-year old girl, was traveling 50 miles north of Trinity Site (where the first atomic bomb was tested) when the atomic bomb was detonated. According to their records, she "saw" the flash of light from the detonation, and said to her brother who was driving the car, "what's that?"
Before the article and news of the detonation were released, the public did not yet know of the bomb's existence; they believed it was an accidental explosion at a munitions dump.
This urban legend is poorly and mysteriously supported and was even tweaked in other publications shortly following the release of the original article. We can use a few of the principles of scientific thinking to evaluate the validity of this urban legend.
First, there is an issue of correlation versus causation; we do not know for sure that the reason Georgia Green said "what's that" had anything to do with the bomb's detonation. A spider could have crawled up her arm, the seat belt could have pinched her finger, a gust of wind could have blown in her face, etc. It could have been a complete coincidence that something else happened at the same time the bomb went off. Which leads us to the next principle: replicability. If she would have been placed in the same situation but at a different time, would the same thing happen? Would she be able to "see" the flash of the bomb again? Lastly, we can evaluate the urban legend using the principle that extraordinary claims require extraordinary evidence. If it so happens that Georgia Green actually saw the flash of the detonation, what is the explanation for such a phenomenon? There would have to be extraordinary evidence to support the argument that blind people acquire or experience some kind of reaction to the radiation produced by the atomic bomb, for example.
