It is a great， big， wide-open sky over our heads， but when you are flying in a jet airliner at 600 miles an hour， the sky is not so big. Thats part of the reason why， in the first four months of this year， the government said only 72 percent of all flights arrived on time， the lowest number since the recent system of reporting began in 1995.

The runways are full， the planes are jammed， and air traffic controllers complain theyre stressed out. And the radar systems that keep things going are， in large part， technology of the 1960s. “Its like driving down the road with a paper bag over your head， and youre trying to stay out of the way of other cars，” says Captain Karen Lee， a 747 pilot who heads operations for UPS， the delivery service.

At its center in Louisville， UPS is experimenting with the next generation in air traffic control： planes guided by the satellites of the Global Positioning System， instead of radar.

Though it has advanced greatly over the years， radar is a technology that dates back to World War II. It scans the sky， looking for signals from planes in the air. Typically， air traffic radar only updates a planes position once every 12 seconds or so — and in 12 seconds， a jet can move two miles or make a turn. Whats more， radar signals can be blocked by storms or mountains. But with GPS signals， pilots can see in real time exactly where they are， and where other planes are， too. A readout screen in the cockpit （駕駛艙） tells the pilots whats around them.

“What we end up with is a very exact location for each aircraft in the system，” said Basil Barimo of the Air Transport Association， which represents airlines.

According to one story， the idea for making the first teddy bear came from a newspaper cartoon drawn in 1904. This cartoon showed President Teddy Roosevelt on a hunting trip refusing to shoot （射殺） a young bear. The young bear became a symbol for Teddy Roosevelt.

Morris Michtom owned a small candy and toy store in New York City. He and his wife made many of the toys they sold. When he saw the cartoon， he had a wonderful idea. He decided to make a toy bear with eyes and legs and arms that moved. The bear was put in the store window next to a copy of the cartoon. Mr Michtom called it “Teddys Bear”.

Many of these bears were sold. The bears became so popular that Mr. Michtom thought he might need President Roosevelt permission to use his name. He wrote to the president and sent him a “Teddy Bear”. The president answered， saying that Mr. Michtom could use his name.

Mr Michtom borrowed money so that he could make thousands of toy bears. His company became the Ideal Toy Corporation. Today this is one of the biggest toy companies in the United States.
