Recently,a solar powered plane took to the sky for the first time. It had passed an important test on the way to travel around the world. The plane took off from an airport in Switzerland at 45km an hour. It slowly rose above the fields and into the sky. "There has never been an airplane of that kind that could fly -- never an airplane so big, so light, using so little energy," said Bertrand Piccard, a leader of the project. During the 90-minute flight, the plane did several turns. It climbed nearly 1.6km above the countryside. Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012. The plane flies at 70 km an hour. That is faster than a bike and slower than a car. Piccard and pilot Andre Borschberg will take the plane around the world. The pilots will keep the plane in the air for up to five days at a time. "We want to fly it day and night with no fuel ," Piccard said How long did the first flight of the solar powered plane last? A) 45 minutes B) 60 minutes C) 70 minutes D) 90 minutes

One Saturday morning, Apple Inc's iPad table computer went on sale in the United States stores across the country. The iPad can be bought in more than 200 U.S. Apple stores from Apple. Many fans even waited overnight outside some Apple stores, hoping to be the first to get one. Dozens of the people were waiting before the door opened at 9:00 a.m. Hiro Kishimoto, a Japanese computer researcher who had a meeting in San Francisco, came as early as 5:00 a.m. He wanted to read books and magazines with the iPad. " It's much more comfortable than a laptop . Because the laptop is too heavy to carry all the time, when you are in the living rooms, maybe the iPad is the best one to use." He said. The iPad models that hit the U.S. Market on Saturday with price starting from 499 dollars, only have Wi Fi link to the Internet. Apple models that have both Wi Fi and 3G will be on sale in Australia, Canada, France, Germany, Italy, Spain, Swizland and the UK in late April. With a 9.7 -inch touch screen like books and magazines, iPad can let users finish many tasks including making the web, watching videos, playing games and reding e-books. Apple is trying to remake the tablet computer. The iPad doesn't support Adobe's Flash software that is used to watch many of the videos on the web.
