Roswell has been so famous in UFOlogy world for over 65 years. However, believers in UFOs have been considered as people who are less credible on what they say. Most people just brush off stories of close encounters and proofs of little green man thinking they are all made-up. Few want to believe, but they are thinking that believing UFOs and aliens is a crazy thing and that the idea of aliens visited earth is only delusional, silly, and misguided.
On January 7, 1948, there was a man named Thomas Mantell whose name was greatly associated with UFO. He was one of elite pilots during WWII with honors including the Distinguished Flying Cross for his courageous action and an Air Medal for his heroism. He spent the last day of his life serving the Kentucky Air National Guard. It is believed that he was the first man who died in pursuit of a UFO.
Mantell was already in the air on January 7, 1948 together with other Kentucky Air National Guard pilots when the base control tower alerted them on a strange object in the sky. The object was observed hovering for a long time before it quickly climbed to 10,000 feet. Mantell and other pilots were ordered to follow it. The object went too high, the reason others stopped their pursuit but Mantell continued on. He may be very determined to know what the object was.
The UFO went at 25,000 feet, but Mantell did not reach it. His plane spiraled into a dive and crashed. The UFO completely disappeared without a single trace. Some concluded that Mantell went too high and did not get sufficient supply of oxygen to breathe, so he lost control of the plane as he blacked out. However, others believed that his plane was shot down by magnetic rays or he was killed by extreme radiation from the UFO.
Only Mantell really knows what had happened on that day. There is no concrete proof that the object was alien in origin, but there is also no concrete evidence to rule out the possibility.
