Forty-two years after the birth of the airplane, we see aviation on the threshold of a great new era of progress. Fighting planes with a speed of nine miles a minute are an actuality. A giant transport plane, capable of carrying 100 passengers, has flown across the continent in six hours. This means that a passenger may eat lunch in New York and dinner in California. It means that postwar air travelers will become accustomed to flying at the speed of our 1939 fighting planes. Air travelers soon will be crossing the country at a speed of eight miles a minute. Boys and girls reading this book will, a few years from now, marvel that we even got excited over the eight-mile-a-minute airplane.
The year 1944 saw a twelve-and-one-half ton fighter go into action on the war fronts. This plane, the Northrop P-61 Black Widow night-fighter, is one of the most powerful airplanes yet to go into action. Powered with two 2,000-horsepower engines, the P-61 flies at 400 miles per hour. Equipped with radar and powerful guns, it can search out an enemy plane at night and destroy it.
The new Bell P-59 Airacomet is America’s first jet-propelled fighter. Its performance has amazed expert test pilots. It has no propeller (note diagram below), and the pilot hears no engine roar or propeller scream. He feels no vibration. Yet he whizzes along at a tremendous speed which is still a military secret. This lack of vibration reduces pilot fatigue, adding hours to his safe flying time.
