It was the final climb on his quest to reach the highest summit on all seven continents. When Christopher Kulish finally reached Mount Everest’s 29,035-foot peak, he joined an elite group known as the “Seven Summits Club”. But the 62-year-old Colorado attorney died suddenly Monday after returning to the first camp below the mountain’s summit. He’s the second American to die in the past week after reaching Everest’s highest point. His family believes the cause was a heart attack, according to the Denver Post. “He saw his last sunrise from the highest peak on Earth,” his brother, Mark Kulish, said in a statement to the Denver Post. “We are heartbroken at this news.”

Last week, 55-year-old Donald Lynn Cash of Utah collapsed and died just after reaching the Everest peak. He too had reached the highest point on all seven continents. Including Christopher and Cash, at least 11 people have died on Mount Everest this year.

The deaths come among reports of overcrowding on the popular mountain. The Nepali government granted a total of 381 permits to climb Everest this year, a number that doesn’t include guides who are on the mountain as well. For some climbers, that traffic has meant longer wait times — some told the Himalayan Times the wait has exceeded two hours between the last camp and the peak. Mountaineer Vanessa O’Brien, who has also climbed the seven summits, said when there’s a crowd, being a more experienced climber won’t help you. “It doesn’t matter if you’re the best racecar driver in the world. If you’re stuck in traffic, you’re stuck in traffic,” she said in an interview.

And when a climber is stuck in that traffic, “their body is starting to deteriorate.” O’Brien, who set a record as the fastest woman to reach the highest peak on every continent, also said the descent is often harder than the climb.

Climbing expert Alan Arnette said there’s no simple explanation for the string of deaths. He said weather that has led to a shorter climbing season is one factor causing overcrowding. He also said the cost to climb Mount Everest has decreased, which means more people are making the journey. He urged the governments in charge of granting permits to limit how many people can be on the mountain at once.

Still, Christopher was no beginner. His family said he’d been mountain climbing for five decades. He arrived at the base camp nearly two months before his climb so he could give himself time to adapt to the conditions. When he made his journey, his family said he was climbing with a small group in almost ideal conditions after some of the overcrowding had cleared.

His brother described being a lawyer as a “day job” for Christopher. Climbing was his passion. “He was an inveterate climber of peaks in Colorado, the West and the world over,” Mark Kulish said. “He passed away doing what he loved.”

The cause of the crash of a China Eastern Airlines aircraft on March 21 has yet to be determined, and rumors (谣传) saying that the analysis of the data of the black boxes has been completed and that the co-pilot is responsible are untrue, an official with the China Aviation Administration of China said, CAAC has noticed that rumors about the tragedy (惨剧) being spread in the name of government bodies and public security departments have been recently circulating online.

Besides blaming the co-pilot for the crash and announcing that the analysis of the black boxes has been completed, some rumors have also stated that the administration has issued an urgent directive requiring pilots to take psychological health assessments. These are all untrue, Wu Shijie, deputy director of the administration’s safety office, told a monthly routine news conference on Monday.

“Those rumors have severely misguided the public and interrupted the investigation. Together with the public security departments, we are trying to find out those who are responsible for spreading these rumors, and they will be handled according to the law,” Wu said. “Authorities are still investigating the cause of the crash, so it’s still too early to draw conclusions.”

The Boeing 737 aircraft, which departed from Kunming, Yunnan province, for Guangzhou, Guangdong province, crashed in Tengxian county of the Guangxi Zhuang autonomous region on March 21. All 132 people on board died.

It’s undeniable (不可否认的) that the crash has caused pilots and airline staff certain degrees of psychological and emotional impact, Wu said. Some of them, especially young employees, have become stressed and depressed. The administration has attached great importance to their mental health conditions, he said. “We asked the airlines to offer psychological support to airline pilots and staff to ensure they are emotionally stable,” he added.

In a close-up (特写), one man is pulling the other with all his strength through the window of an SUV, a type of vehicle, which is stuck dangerously on a cliff (悬崖) 30 feet above a busy roadway.

Jason Warnock, then 29, is the man performing the life-saving action. He was driving in Lewiston, Idaho, in April 2015 when he came upon a fallen tree in the middle of the road. “I was like, ‘What happened’?” he told a news website. Warnock stretched out his neck to stare up the side of a cliff. At the very top, where the tree should have been, was an SUV swinging on the edge, held back from falling to the road by a delicate, heavily damaged chain-link fence. Looking inside the car, Warnock could see a panicked Matthew Sitko, 23, beating on the passenger-side window.

That’s when Warnock sprang into action. He crossed a nearby footbridge, and climbed up the cliff to get to the vehicle. When Warnock got to the car, he tried breaking the window with a tool he had on him, only to realize that his cracking was shaking the car and might cause it to slip down the hill. He stopped and turned to calming Sitko enough to get him to open the window. “Give me your hand,” Warnock said. “If this thing goes, I want to have a hold of you so I can at least get you out of there.” Before reaching for the lifeline, Sitko had one request: “Can I grab my phone?” Soon enough, Warnock had freed both man and his machine.

According to the Lewiston police chief, the accident was caused when Sitko, who suffered only minor injuries, lost control of his car. For his part, Warnock insisted he came to Sitko’s aid for one simple reason: “I just did what anyone would do.”
