Earth’s magnetic North Pole has drifted so fast that authorities have had to officially redefine the location of the magnetic North Pole. The extreme wandering of the North Pole caused increasing concerns over navigation, especially in high latitudes.

Earth’s magnetic field is known to have wandered and flipped in the geologic past. Earth’s magnetic field is a result of spinning molten iron and nickel 1,800 miles below the surface. As the constant flow of molten metals in the outer core changes over time, it alters the external magnetic field.

How soon will supersonic jets return to our skies?

by Paul Sillers, CNN Travel

A new era of supersonic flight might be just around the corner, but there are three challenges to overcome when it comes to flying faster than the speed of sound.

Those are the three Es of aviation: engineering, environment and economics.

Concorde, the aeronautical marvel that made its last flight 16 years ago this week, only conquered the first of those three travel challenges.
