The Great Daylight 1972 Fireball (or US19720810) was an Earth-grazing meteoroid which passed within 57 kilometres (35.4 miles) of the surface of the Earth at 20:29 UTC on August 10, 1972. It entered the Earth's atmosphere in daylight over Utah, United States (14:30 local time) and passed northwards leaving the atmosphere over Alberta, Canada. It was seen by many people and recorded on film and by space-borne sensor
If it had not entered at such a grazing angle, this meteoroid would have lost all its velocity in the upper atmosphere, possibly ending in an airburst, and any remnant would have fallen at terminal velocity.

The last large meteor to enter Earth's atmosphere occurred less than 100 years ago. On June 30, 1908, a meteor sped toward Earth at such an angle that it entered the atmosphere in an area over Siberia, causing an explosion, but continuing on out into space. In essence, it skipped across our atmosphere like a stone on a smooth pond. Fortunately, the region, known as Tunguska, is sparsely populated and no one was killed in the explosion, which leveled 500 square miles of forest.
Another meteor gave a glancing blow to Earth's atmosphere even more recently. On August 10, 1972, the blue sky above the gorgeous mountain scenery in Grand Teton National Park was pierced by a meteor that was captured on video sailing across the sky. The object was later estimated to be approximately 10 meters wide and several thousand tons in weight.
