Floating on Air

Today's History Lesson

Throughout history, man has been intent on improving upon ideas of moving machines for purposes of transport. One of the most successful inventions of the 20th century emerged as a result of some very unusual testing.

This Day in History: May 31, 1959

The principle behind today's hovercraft was first demonstrated by Sir Christopher Cockerell in 1955 using an empty KiteKat cat food tin inside a coffee tin, an air blower (some sources cite a hairdryer) and a pair of kitchen scales. The first manned hovercraft flight took place on May 31, 1959 with the seven-ton SR.N1 developed by John Cockerell making its first test flight. It was capable of a speed of 60 knots.

The concept behind the hovercraft actually began centuries ago being traced back to the early 1700's, and ideas for flying machines date back to ancient Greece. Cockerel's idea allowed a vehicle to move over water's surface, floating on a layer of air, thus, reducing friction between the vehicle and the water.

An Illustrated History of the Hovercraft

The money Cockerell received for his hovercraft patent didn't cover his development costs. As with so many inventors and creative individuals, he remained bitter with lack of compensation and capitalization of such an inventive idea. It is interesting to note the US naval hovercraft is still in use today.

10 Mind-Blowing Pictures, Videos of a Zubr-class Hovercraft, the World's Largest

You haven't seen a hovercraft, until you've seen the Zubr-class, a class of air-cushioned landing craft of Soviet design that's currently the world's largest. It's designed to sealift landing assault units (such as marines or tanks) from equipped/non-equipped vessels to non-equipped shore, as well as transport and plant mines. Read MORE...
