The Great Daylight 1972 Fireball

El 10 de Agosto de 1972 una bola de fuego surcó la atmósfera terrestre desde Utah a Alberta durante 101 segundos, recorriendo una distancia de 1000 millas a una velocidad de 14'7 kilómetros por segundo. El asteroide fue filmado por Linda Baker desde el Parque Nacional Grand Teton y un satélite de la fuerzas armadas estadounidenses detectó por radiometría de infrarojos la alteración atmosférica. De un tamaño de entre 2 a 80 metros de diámetro, de haber impactado en la superficie, habría formado un cráter del tamaño de una ciudad mediana.

The outro was annoying as fuck, but great video! I liked the music. It makes you curious to know what those people were thinking this might be back then, like what if it were another Roswell? If only... heh

I dont think people understand this. The camera was probably over 500 miles away from the actuall fireball. This was PROBABLY traveling at about 3 miles per second. If you were to not be encased in any structure and traveled at this speed, 2 things would happen. You would die instantly, and let say you Survived some how. You would be traveling at about 10 times the speed of sound. the wind hitting the outside of your ear would be fast enough to go in. And then all the sound would catch up. Ouch.
