When an American introduced the Boeing 707 in 1958, it speeded up the mail considerably. Powered by four turbojet engines, the 707 has a wingspan of over 130 feet and a length of nearly 145 feet. These jets carried a 46,153 pound payload and cruised at 570 miles per hour over very long distances, slashing flying times almost in half! In 1970, the world’s first jumbo jet, the Boeing 747, increased the efficiency of mail delivery even more. 1949 Perforated 11 x 101/ 2 C40 6¢ Alexandria, VA........ .45 .20 Perforated 10 Horizontal Coil C41 6¢ DC-4 Skymaster(mint pair $12.25)......... 5.25 .15 C42 C43 Post Office Building Globe & Doves C44 C45 Boeing Stratocruiser Wilbur & Orville Wright Scott Number Mint Used 1949 Rotary Press PrintingC42-44 Universal Postal Union, 3 Stampscomplete.
