A New Long Distance Shot Record

May 8, 2010

A new record has been set for the long distance shot at a distance of 1.52 miles.

A British sniper set a world sharpshooting record by taking out two Taliban soldiers in Afghanistan from more than a mile and a half away — a distance so great, experts say the terrorists wouldnt have even heard the shots.

Craig Harrison killed the two insurgents from an astounding distance of 8,120 feet — or 1.54 miles — in Helmand Province last November firing an Accuracy International L11583 long-range rifle.

“The first round hit a machine-gunner in the stomach and killed him outright,” said Harrison, a corporal of horse in the British Armys Household Cavalry, the equivalent of a sergeant in the American military.

Is Mt. Everest the Highest Mountain? It Depends!

February 9, 2010

If you measure the distance to the peak of Mount Everest from sea level, then it is the highest mountain.   But if you were to measure from the center of the earth to the peak, then Mount Chimborazo in Ecuador would be considered the highest mountain on Earth.   By this measurement, Mt. Everest would be the 5th highest peak.

The summit of Mount Everest reaches a higher elevation above sea level, but the summit of Chimborazo is widely reported to be the farthest point from Earth’s center, although Huascarán is a near-tie second. Chimborazo is one degree south of the equator and the Earth’s diameter at the equator is greater than at the latitude of Everest
