Page "Impact event" Paragraph 35

On August 10, 1972, a meteor which became known as The Great Daylight 1972 Fireball was witnessed by many people moving north over the Rocky Mountains from the U. S. Southwest to Canada.

It was filmed by a tourist at the Grand Teton National Park in Wyoming with an 8-millimeter color movie camera.

The object was in the range of size from a car to a house and could have ended its life in a Hiroshima-sized blast, but there was never any explosion.

Analysis of the trajectory indicated that it never came much lower than off the ground, and the conclusion was that it had grazed Earth's atmosphere for about 100 seconds, then skipped back out of the atmosphere to return to its orbit around the Sun.
