Three theories
Amelia Earhart, the first woman to fly alone across the Atlantic Ocean, was attempting a round- the-world flight in 1937. She planned to land on the tiny Pacific Ocean island of Howland. She never arrived. Her fate, and that of her navigator (导航员)Fred Noonan, remains one of aviation’s (航空的)greatest unsolved mysteries. Researchers have spent millions of dollars investigating the case and several books have been published that examined different theories.
The official US position is that Earhart ran out of fuel and crashed in the Pacific Ocean. The radio log from aUS Coast Guard ship indicates that she must have been near Howland when contact was lost
Another theory says that Earhart could have crashed on a different island, called Nikumaroro, and died since the island is uninhabited.
Yet another theory claims she was captured while on a secret mission to the Marshall Islands in the North Pacific and eventually returned to the US with a new identity.
Lost and found?
The missing pilot
February 18, 2011
Amelia Earhart’s dried saliva (唾液)could help solve the longstanding mystery of the aviator’s 1937 disappearance, according to scientists who plan to take samples of her DNA from her correspondence. A new project aims to create a genetic profile that could be used to test recent claims that a bone found on the South Pacific island ofNikumaroro is Earharf s.
Justin Long, a Canadian whose family is partially funding the DNA project, points out that at the moment, anyone who finds parts of bones can claim that they are Earhart’s remains. According to Justin Long, Earhart's letters are the only items that are both proved to be hers and that might contain her DNA. Hair samples are one of the best sources of DNA, but no hair samples from Earhart are known. There was, in theory, a sample of Earhart's hair in the International Women’s Air and Space Museum in Cleveland, US. However, a 2009 study revealed that the sample was actually thread.
The remains of Earhart, her navigator Noonan, and their twin-engine plane were never recovered. But in 2009, a group of researchers found a bone fragment on Nikumaroro that they believed might have been from one of Earhart' s fingers. However, some scientists have suggested the Nikumaroro bone fragment isn’t human at all but may instead belong to a sea turtle that was found nearby.
The new Earhart DNA project will be headed by Dongya Yang, a genetic scientist at Simon Fraser University in Canada. Yang will work on four letters Earhart wrote to her family. Much of Earhart's correspondence was done by her secretary but the assumption is that Earhart must have sealed the envelopes of these personal letters herself.

2 . Coming of age is that time in each of our lives when we begin to see the possibilities. The world opens up in ways that mature our vision and give us a sense of responsibility and gratefulness. Connor had just started college and loved being at that stage in his life where he could eat all the pizza he wanted, yet engage in adult conversations with his parents about the responsibility to make life better for others. Connor’s optimism was infectious. There was so much he could do, and so much he could become.
But it all ended one night when Connor was distracted while driving on a Colorado highway. A young man, who gave off so much light, suddenly went dark.
Connor’s father, David, took it particularly hard.A father sees more than his own traits(性格) in his son; he sees greater possibilities than he achieved. Taking that hope away left David feeling at a loss. But Connor ‘s optimism was one of those traits passed on to him by his father. So, David got to work.
First, he established the Honor Connor Scholarship Fund to reward students who served in the community, Next, he went to work creating a research-based curriculum that educates University of Colorado Boulder students and their families about the dangers of texting while driving. It includes a very simple three part promise: Do not text or use social media while driving, speak out if riding with a driver who is distracted and encourage friends and family to drive phone-free.
David now works with lecturers at various colleges’ and high schools, ensuring young minds understand how statistically at risk they are when they text while driving. He’s become a passionate advocate for preparing young people to drive safely and not reach for their phones while they’re at the wheel. “I just don’t want other parents to go through what I did when I lost Connor,” says David. “It’s just so preventable.”

4 . It was rush hour on the morning of June1. Heather Santellano, 36, was driving her car on Houston Harte Frontage Road with her nine-year-old daughter and ten-year-old son in the back. Suddenly, a red pickup truck cut them off. Santellano turned the wheel hard to the right, sending the car running off the road and down an embankment (路堤) that ended in a drop-off after about 50 feet. If the car didn’t stop, it would go up into the air and slide onto the road some 20 feet below. Then came a bit of luck. As the car raced towards the edge, its undercarriage got stuck on the embankment, stopping it cold. The occupants, however, were far from safe. The car had come to rest on top of a retaining wall, literally teetering on the edge of disaster. One sudden move by anyone inside could send it over.
Jacob Rodriguez, a veteran, watched the scene unfold from the company where he works. Then, he and four other men ran to the car. They leaped onto the trunk to balance the weight as the terrified kids in the back seat watched.
Meanwhile, Julio Vasquez and his nephew, Marco Vasquez, were driving to their jobs at nearby Premier Automotive. Julio jumped out of the car to help while Marco went to the shop, grabbed a heavy-duty strap and returned to the dangling car. He tied the car to and F-350 truck that had been driven over by one of the other rescuers. With the car secured the group carefully opened the back doors and helped the children out.
But their departure shifted the car’s weight, causing it to lean forward. The men, still on the trunk, implored Santellano to jump into the back seat to re-balance the weight. She did and then inched out from the back door. Finally, the men carefully got off the trunk Everyone was safe. “Another foot,” Rodriguez told the media, “and this would be different story.”

9 . “Mayday! We got Mayday!” Frank Pisano screamed over the micro-phone to the air control tower at John Wayne Airport last June. One of the two engines on his 1975 Cessna had failed, and he was now on a collision course with one of the busiest highways in America—Interstate 405, just south of Los Angeles—and there was no stopping it.
Driving south on the 405, near the airport’s runway, was John Meffert. A fire department captain, Meffert, 47, was heading home from his shift. Then a low-flying plane caught his eye. After he took a second glance, a thought crossed his mind: “This plane’s going to hit me,” Meffert told Fox 8.
He was right. The plane knocked into the center highway, popped up a few feet, and then hit the front of Meffert’s SUV. It finally stopped after hitting the divider on the southbound side. Meffert pulled over. He was unhurt, so he turned his attention to the plane. He ran toward the smoke billowing from it—and then he saw Frank’s wife, Janan Pisano, pop her head up on the passenger side.
By the time Meffert reached the aircraft, part of the fuselage (机身) was on fire and Janan, who was covered in blood, was on the wing trying to pull her husband from the wreck. Meffert, afraid the plane would explode, guided her to safety behind it. At this point, traffic had come to a stop, and two nurses jumped out of their cars to help lead Janan farther away as Meffert ran back for the pilot.
“I’m going to get you out,” Meffert said as he positioned himself under the pilot’s arms and carefully lifted him from the seat. He dragged the pilot off the wing and carried him to the side of the freeway to safety, where they watched flames swallow the plane.
Remarkably, Meffert’s car was the only one hit by the plane. Had Meffert been a second or two faster, Frank told the Orange County Register, the left propeller (螺旋桨) would have torn the top off his SUV and killed him.
“I play all the what-ifs—going slower, going faster. It could have been in a very different situation,” Meffert told Fox 8. “We just had a lot of angels.”

10 . NEW DELHI—Indian Prime Minister Narendra Modi Tuesday inspected the bridge collapse site in the western state of Gujarat, where more than 100 people were killed, officials said. Ahead of the visit, Modi chaired a high-level meeting on Monday night during which he was briefed about rescue efforts.
The century-old British-era pedestrian suspension bridge (吊桥) collapsed on Sunday evening, with hundreds of people falling into Machchhu River in Morbi town, about 241 km west of the capital city, Gandhinagar. Reports said that 177 people were rescued and over 100 people were undergoing treatment at the Morbi civil hospital.
Soon after the bridge visit, Modi reached the civil hospital in Morbi to meet the injured. The prime minister was seen asking the survivors about their health. According to officials, search and rescue operations, carried out by teams of the State Disaster Response Force and the National Disaster Response Force (NDRF), the Indian navy, the Indian air force and the Indian army, were called off (取消) on Monday evening and began again on Tuesday morning. Officials said Modi also met with those involved in rescue and relief operations.
The local government of Gujarat has already ordered an investigation into the deadly collapse of the bridge. The bridge is a popular tourist attraction in the area. It was shut for renovation (整修) for seven months and was open for the public on Oct 26, the Gujarati New Year.
Reports said that around 500 people, much beyond its capacity, were on the suspension bridge at the time when it crashed into the river.
Police have arrested nine people including officials of Oreva, the company that carried out the repair work, ticket sellers and security men. However, the owners of the company have not been arrested. Oreva group is actually a Gujarat-based watchmaker company. Reports said that the watchmaker reportedly outsourced (转包) the “technical aspect of the renovation” to a smaller construction company, Devprakash Solutions.
Oreva has been accused of violating multiple safety rules, leading to the huge tragedy just four days after the bridge reopened to the public. Questions have been raised over why Oreva with no experience in construction was given responsibility for maintaining a bridge.
