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.

4.We can infer from the passage that ______.
A.All the controllers in the US were working alone while they were on duty |
B.The incidents are rooted in fatigue problems and those on midnight shifts need an extra nap |
C.In the U.S. , thousands of people expect to work through the night in safety-critical jobs |
D.The agency has added an extra controller at the 27 towers |
Beijing ?(13, July) China sent up a new data relays atellite (数据中继卫星), Tianlian I -02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province.The new satellite will promote the country's satellite communication network for space docking (对接).
The satellite was launched on a Long-March-SC carrier rocket at 11:41 p.m., sources at the centre told Xinhua News Agency.The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit (地球同步转移轨道).
Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country's second data relay satellite.The first, Tianlian I -01, was launched on April 25.2008.
The two satellites will form a network to improve communications between China's spacecraft and bases on Earth, according to the centre.They will also be used to help the nation's first space docking, scheduled for the second half of this year.
As planned, China will launch space module Tiangong-I (天宫1号), which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county's first space-docking mission this year.
Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites.
"The new satellite can cover a greater area to track and command the country's space vehicles m low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position m outer space.Only three satellites of this kind are needed to form a global communication network, and China has two now." Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said.
The satellite could also equip astronauts with real-time communications, which will benefit the county s future manned space flights, he said.
1.What is the main purpose to send up Tianlian I -02 ?
A.To test the function of a Long-March-SC carrier rocket. |
B.To carry some astronauts into space to do some research. |
C.To send more information and clearer pictures to mobile phones on the earth. |
D.To promote the country's satellite communication network for space docking' |
2.From the passage we know .
A.one more such satellite is needed to form a global communication network |
B.the satellite was developed by China Manned Space Engineering Office |
C.it was less than three years since China launched its first date relay satellite of this kind |
D.the satellite could help track and command space vehicles in orbits because it's lower in position |
3.Which of the following is TRUE according to the news report?
A.Shenzhou Ⅷ is a manned spaceship. |
B.Tiangong- I will dock with three Shenzhou spaceships next year. |
C.the satellite is of great importance to China's space exploration. |
D.china’s first ^a06 docking will be done in the second half of next year. |
4.The best title of the passage could be _____.
A.China Launched a New Space Shuttle |
B.China's Plan for Space Exploration |
C.China’s Progress m China's Space Exploration |
D.New Satellite Helps China's Space Exploration |
