Co-Axial Rotors. as on the Hiller-copter illustrated in the December Mechanix Illustrated, eliminate noise and vibration on this new helicopter designed by Vincent Bendix. The inventor claims it will be easier to operate and safer than an automobile. Two levers control the machine’s flight, and continuous autorotation makes it possible to fly it with safety at altitudes of only 100 to 200 feet.
Harold H. “Kiddy” Karr was a pioneering naval aviator (Enlisted Naval Aviation Pilot Certificate #1). He passed away in 1978.
Navy Flyer Invents Tandem Airplane for Heavy Loads
A TANDEM airplane called the KarrAvan has been invented by Harold H. Karr, a naval aviation pilot at North Island, San Diego, California. The ship which is 130 feet long and has a wing spread of 96 feet is able to lift 85,000 pounds. The unique flying machine will be powered by five 420 h.p. engines and will have a top speed of 135 miles an hour. The ship will carry 80 passengers and their baggage more than 4,000 miles without a halt.
Landing On An Automobile!
ONE of the most unusual aerobatic stunts ever achieved was photographed recently at an air show, where Dannie Fowlie, stunt flier, successfully took off in his plane from the top of an automobile, and then managed a landing on the car top.
How a Metal “Man” Pilots Plane
Is the day of the airplane which will be piloted by pushing a button almost here? A new gyroscopic control keeps an airplane on an even keel and on a predetermined course more accurately than the most experienced human pilot.
A MECHANICAL pilot, a small instrument weighing only 50 pounds and small enough to be stowed away under a chair, recently piloted a tri-motored airplane on a three-hour flight between Dayton and Washington far more accurately and with greater precision than the most accomplished human pilot.
Latest Jet Plane is this new Consolidated Vultee XP-81, the first plane ever to fly with a gas turbine engine designed for propeller drive. Powered by a gas turbine engine in the nose and a jet engine in the tail, the sleek fighter will fly at a speed of more than 500 mph. At the right is a cutaway sketch showing the placement of the turbine and jet engine.
Science in Pictures
Push-Button Telegraph center permits messages to be typed only once, on a “printer perforator,” at point of origin. When messages reach the center, a clerk pushes a button for the city of destination.
Fishy Idea dreamed up by amateur inventor Dr. Carl Omeron, right, looks like a spark of genius. This is it: Tie balloons to a live “Judas” fish (which you catch the hard way). Put Judas back in the water and he’ll lead the way to the whole school.
NEW in the AIR
AVRO VULCAN delta-wing bomber is powered by lour Armstrong Siddeley Sapphire let engines, each of which gives 8.300 pounds of thrust, a power equivalent of our World War II Superforts.

And yes, both the Air Force and NASA say it went into space.
