WASHINGTON---At least four more U.S. air-traffic controllers are caught nodding off on the job at three separate airports across the nation, the government said Wednesday.
The controller working alone in the tower fell asleep and was out of communication for 16 minutes while a medical flight carrying a patient was trying to land at about 2 A.M. Wednesday at Reno-Tahoe International Airport in Nevada, the Federal Aviation Administration (FAA) said in a statement.
The FAA announced that it is also investigating a controller who fell asleep Monday at Boeing King County International Airport in Seattle and two controllers who were unresponsive at McGhee Tyson Airport in Knoxville, Tennessee on Feb.19.
“I am sick of this,” Senate Commerce, Science and Transportation Chairman Jay Rockefeller, a West Virginia Democrat, said in a statement. “We can’t have a system where some of the people responsible for safety are asleep at the switch.”
As the incidents pile up, sleep experts say it demonstrates that the agency faces a systemic issue with the thousands of people expected to work through the night in safety-critical jobs. Scientific research shows that workers on midnight shifts make more errors because it is so difficult for the body to adapt to sleeping during the day, they say.
The agency will add an extra controller at the 27 towers staffed with one worker on the midnight shift, the FAA statement said.
Representative John Mica, the Florida Republican who chairs the House transportation committee, criticized the decision to add controllers. “Only in the federal government would you double up on workers, averaging $161,000 per year in salary and benefits, that aren’t doing their job,” Mica said in a statement. Mica has pushed legislation that would allow as many as 90 smaller airports to switch from federal to private controllers.
“People have known these problems with fatigue（疲劳）have existed for years,” said John Goglia, a Boston-based aviation safety consultant. “They’re now showing up. The FAA is admitting they exist. Now the FAA needs to work on it.”
The four controllers in Nevada, Seattle and Texas have been suspended(暂时停职) during the investigations, the FAA said.

Jeffrey Bezos, founder, president and chairman of the board of Amazon.com, was born in Albuquerque, New Mexico. His mother’s ancestors were early settlers in Texas, and over the generations had acquired a 25,000 acre farm at Cotulla. Jeffrey spent most summers of his youth working with his grandfather on their farm.
Jeffrey showed intense and varied scientific interests at an early age. He set up an electric alarm to keep his younger sisters and brothers out of his room and changed his parents’ garage into a laboratory for his science projects.
After he graduated from Princeton University with a degree in computer science and electrical engineering, Jeffrey Bezos found employment on Wall Street, where computer science was increasingly in demand to study market trends. He rose quickly, becoming a senior vice president, and looked forward to a bright career in finance, when he made a discovery that changed his life, and the course of business history.
In 1994, there was still no internet commerce to speak of. One day that spring, Jeffrey Bezos observed that Internet usage was increasing by 2300 percent a year. He saw an opportunity for a new circle of commerce, and immediately began considering the possibilities.
Bezos founded Amazon.com in 1994, setting up the original company in his garage. The company was called Amazon for the seemingly endless South American river with its numberless branches. It started as an online bookstore but soon diversified to all kinds of products. His work with Amazon eventually led him to become one of the most excellent dot-com entrepreneurs. He was named Time magazine’s Person of the Year in 1999. In 2008, he was selected by U.S. News & World Report as one of America’s Best Leaders. Bezos’ Amazon has become “the Earth’s biggest anything store”. Amazon.com is now called “one of the smartest strategies in business history”.
Today, Jeffrey Bezos lives north of Seattle and is increasingly concerned with charity activities. “Giving away money takes as much attention as building a successful company,” he said.

As a physician who travels quite a lot, I spend a lot of time on planes listening for that dreaded “Is there a doctor on board?” announcement. I’ve been 16 only once — for a woman who had merely fainted. But the 17 made me quite curious about how 18 this kind of thing happens. I wondered what I would do if 19 with a real midair medical emergency — without access 20 a hospital staff and the usual emergency equipment. So 21 the New England Journal of Medicine last week 22 a study about in-flight medical events, I read it 23 interest.
The study estimated that there are a(n) 24 of 30 in-flight medical emergencies on U.S. flights every day. Most of them are not 25 ; fainting and dizziness are the most frequent complaints. 26 13% of them — roughly four a day — are serious enough to 27 a pilot to change course. The most common of the serious emergencies 28 heart trouble, strokes, and difficulty breathing.
Let’s face it: plane rides are 29 . For starters, cabin pressures at high altitudes are set at roughly 30 they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty 31 , but passengers with heart disease 32 experience chest pains as a result of the reduced amount of oxygen flowing through their blood. 33 common in-flight problem is deep venous thrombosis — the so-called economy class syndrome (综合症). 34 happens, don’t panic. Things are getting better on the in-flight-emergency front. Thanks to more recent legislation (立法), flights with at 35 one attendant are starting to install emergency medical kits to treat heart attacks.
