A large UPS cargo plane slammed into a field near an airport in Birmingham, Ala., shortly before dawn, the Federal Aviation Administration said on Wednesday.

The pilot and co-pilot were killed in the crash, Birmingham Mayor William Bell said. A spokesman for UPS said they were the only two crew members aboard the plane. There were no reports of additional injuries.

The plane, an A300 airbus en route to Birmingham from Louisville, crashed on its approach to the Birmingham-Shuttlesworth International Airport at approximately 6 a.m. EST. According to flight-tracking service FlightAware.com, the flight took off from Louisville International Airport at 5:04 a.m. and was in the air for approximately 45 minutes.

According to Birmingham’s WVTM-TV, the open field where the plane went down is owned by the airport. Neighbors told the network they heard “a large boom and then several other explosions.” Another neighbor told Fox’s WAGA-TV he was awoken by a “sonic boom.”

Fire and smoke could be seen rising from a field in photos and video from local news outlets. The nose section of the plane is still intact, Bell said in an interview with CNN, but “debris is everywhere.”

A spokeswoman for the airport said the crash occurred outside the airport’s perimeter and no other flights were affected.

Investigators with the National Transportation Safety Board were on their way to the crash site, the NTSB said.

“At this time, we are still determining the details of the incident,” the UPS said. “We will release more information as it becomes available. As we work through this difficult situation, we ask for your patience, and that you keep those involved in your thoughts and prayers.”

In a separate statement, UPS Airlines president Mitch Nichols called the incident “very unfortunate.”

“We place the utmost value on the safety of our employees, our customers and the public,” Nichols said. “We will immediately engage with the National Transportation Safety Board’s investigation, and we will work exhaustively on response efforts.”

SAN FRANCISCO: Nearly a week after Asiana Flight 214 collided with a rocky seawall just short of its intended airport runway, investigators have pieced together an outline of the event — what should have been a smooth landing by seasoned pilots turning into a disaster.

With each new bit of information, the picture emerging is of pilots who were supposed to be closely monitoring the plane’s airspeed, but who didn’t realize until too late that the aircraft was dangerously low and slow. Nothing disclosed so far by the National Transportation Safety Board investigators indicates any problems with the Boeing 777’s engines or the functioning of its computers and automated systems.

“The first thing that’s taught to a pilot is to look at the airspeed indicator. It is the most important instrument in the cockpit,” said Lee Collins, a pilot with 29 years and 18,000 hours experience flying a variety of airliners. “Airspeed is everything. You have airspeed, you live. You don’t, you die.”

Investigators are still trying to nail down hundreds of details about the crash last Saturday that killed two people and injured dozens. NTSB Chairman Deborah Hersman has cautioned against reaching conclusions.

But investigators already know a great deal. They’ve listened to the Boeing 777’s voice recorder, which captured the last two hours of conversation in the cockpit. They’ve downloaded its flight data recorder, which captured 1,400 indicators of what was happening on the plane, from the temperatures inside and out to the positions of cockpit instruments.

SAN FRANCISCO: The pilot at the controls of an Asiana plane that crash landed was guiding a Boeing 777 into the San Francisco airport for the first time, and tried but failed to abort the landing after coming in too slow to set down safely, aviation and airline officials said Sunday.

It was unclear if the pilot’s inexperience with the aircraft and airport played a role in Saturday’s crash. Officials were investigating whether the airport or plane’s equipment could have also malfunctioned.

Also Sunday, San Mateo County Coroner Robert Foucrault said he was investigating whether one of the two teenage passengers killed Saturday actually survived the crash but was run over by a rescue vehicle rushing to aid victims fleeing the burning aircraft. Remarkably, 305 of 307 passengers and crew survived the crash and more than a third didn’t even require hospitalization. Only a small number were critically injured.

Deborah Hersman, head of the National Transportation Safety Board, said the slow speed of Flight 214 in the final approach triggered a warning that the jetliner could stall, and an effort was made to abort the landing but the plane crashed barely a second later.

At a news conference, Hersman disclosed the aircraft was traveling at speeds well below the target landing speed of 137 knots per hour, or 157 mph.

“We’re not talking about a few knots,” she said.

Hersman described the frantic final seconds of the flight as the pilots struggled to avoid crashing.

Seven seconds before the crash, pilots recognized the need to increase speed, she said, basing her comments on an evaluation of the cockpit voice and flight data recorders that contain hundreds of different types of information on what happened to the plane. Three seconds later, the aircraft’s stick shaker — a piece of safety equipment that warns pilots of an impending stall — went off. The normal response to a stall warning is to boost speed and Hersman said the throttles were fired and the engines appeared to respond normally.

At 1.5 seconds before impact, there was a call from the crew to abort the landing.

The details confirmed what survivors and other witnesses said they saw: an aircraft that seemed to be flying too slowly just before its tail apparently clipped a seawall at the end of the runway and the nose slammed down.

Pilots normally try to land at the target speed, in this case 137 knots, plus an additional five more knots, said Bob Coffman, an American Airlines captain who has flown 777s. He said the briefing raises an important question: “Why was the plane going so slow?”

The plane’s Pratt & Whitney engines were on idle and the pilots were flying under visual flight rules, Hersman said. Under visual flight procedures in the Boeing 777, a wide-body jet, the autopilot would typically have been turned off while the automatic throttle, which regulates speed, would been on until the plane had descended to 500 feet in altitude, Coffman said. At that point, pilots would normally check their airspeed before switching off the autothrottle to continue a “hand fly” approach, he said.

There was no indication in the discussions between the pilots and the air traffic controllers that there were problems with the aircraft.

The airline said Monday in Seoul that the pilot at the controls had little experience flying that type of plane and was landing one for the first time at that airport.

Asiana spokeswoman Lee Hyomin said that Lee Gang-guk, who was at the controls, had nearly 10,000 hours flying other planes but only 43 in the 777, a plane she said he still was getting used to flying. Another pilot on the flight, Lee Jeong-min, had about 12,390 hours of flying experience, including 3,220 hours on the 777, according to the Ministry of Land, Infrastructure and Transport in South Korea. Lee was the deputy pilot, tasked with helping Lee Gang-guk get accustomed to the 777, according to Asiana Airlines.

Among the questions investigators are trying to answer was what, if any, role the deactivation of a ground-based landing guidance system due to airport construction played in the crash. Such systems help pilots land, especially at airports like San Francisco where fog can make landing challenging. The conditions Saturday were nearly perfect, with sunny skies and light winds.

The flight originated in Shanghai, China, and stopped over in Seoul, South Korea, before making the nearly 11-hour trip to San Francisco. The South Korea-based airline said four South Korean pilots were on board, three of whom were described as “skilled.”

Among the travelers were citizens of China, South Korea, the United States, Canada, India, Japan, Vietnam and France. There were at least 70 Chinese students and teachers heading to summer camps, according to Chinese authorities.

Fei Xiong, a Chinese passenger , was traveling to California so she could take her 8-year-old son to Disneyland. The pair was sitting in the back half of the plane. Xiong said her son sensed something was wrong.

“My son told me: ‘The plane will fall down, it’s too close to the sea,'” she said. “I told him: ‘Baby, it’s OK, we’ll be fine.'”

When the plane hit the ground, oxygen masks dropped down, said Xu Da, a product manager at an Internet company in Hangzhou, China, who was sitting with his wife and teenage son near the back of the plane. When he stood up, he said he could see sparking — perhaps from exposed electrical wires.

He turned and could see the tail where the galley was torn away, leaving a gaping hole through which they could see the runway. Once on the tarmac, they watched the plane catch fire, and firefighters hose it down.

“I just feel lucky,” said Xu, whose family suffered some cuts and have neck and back pain.

In the chaotic moments after the landing, when baggage was tumbling from the overhead bins onto passengers and people all around her were screaming, Wen Zhang grabbed her 4-year-old son, who hit the seat in front of him and broke his leg.

Spotting a hole at the back of the jumbo jet where the bathroom had been, she carried her boy to safety.

“I had no time to be scared,” she said.

Authorities immediately closed the airport and rescuers rushed to the scene. A United Airlines pilot radioed the control tower, saying: “We see people … that need immediate attention. They are alive and walking around.”

“Think you said people are just walking outside the airplane right now?” the controller replied.

“Yes,” answered the pilot of United Flight 885. “Some people, it looks like, are struggling.”

At the crash scene, police officers provided knives to crew members inside the burning wreckage so they could cut away passengers’ seat belts. Passengers jumped down emergency slides, escaping from billowing smoke that rose high above the bay. Some passengers who escaped doused themselves with water from the bay, presumably to cool burns, authorities said.

By the time the flames were out, much of the top of the fuselage had burned away. The tail section was gone, with pieces of it scattered across the beginning of the runway.

Foucrault, the coroner, said senior San Francisco Fire Department officials notified him and his staff at the crash site on Saturday that one of the 16-year-olds who was killed may have been struck on the runaway. Foucrault said an autopsy he expects to be completed by Monday will involve determining whether the girl’s death was caused by injuries suffered in the crash or “a secondary incident.”

He said he did not get a close enough look at the victims on Saturday to know whether they had external injuries.

Foucrault said one of the bodies was found on the tarmac near where the plane’s tail broke off when it slammed into the runway. The other was found on the left side of the plane about 30 feet away from where the jetliner came to rest after it skidded down the runway.

SAN FRANCISCO: An Asiana Airlines flight packed with more than 300 people slammed onto the runway while landing at San Francisco airport Saturday and caught fire, forcing many to escape by sliding down the emergency inflatable slides and into a trail of metal debris as flames tore through the plane.

At least two people who were found outside the wreckage died in the crash, while another 182 people were taken to hospitals, many with minor injuries, authorities said. Forty-nine people were reported to be in critical condition, San Francisco International Airport spokesman Doug Yakel said.

As the plane approached the runway from the waters of San Francisco Bay around noon, travelers in the terminals and others eyewitnesses could see that the aircraft was swaying unusually from side to side and that at one point the tail seemed to hit the ground before breaking off.

Kate Belding, who was jogging a few miles away, said she thought: “Oh my God. That plane is crashing.”

By the time the flames were out, much of the top of the Boeing 777’s fuselage had burned away. The tail section was gone, with pieces of it scattered across the beginning of the runway. One engine appeared to have broken away. Emergency responders could be seen walking inside the burned-out wreckage.

News of the crash spread quickly on Twitter and the Internet in this wired city, with eyewitnesses tweeting their stories, posting images of the plumes of smoke rising above the bay and uploading video of passengers fleeing the burning plane.

“It just looked really bad,” Belding said. “I’ve seen the pictures of it since then, and it’s amazing anyone walked out of that plane.”

The investigation has been turned over to the FBI and terrorism has been ruled out, San Francisco Fire Chief Joanne Hayes-White said. Federal aviation and transportation investigators were heading to the scene. Asiana, Boeing and the engine manufacturer, Pratt & Whitney, pledged to work with them.

Vedpal Singh, who was sitting in the middle of the aircraft and survived the crash with his family, said there was no forewarning from the pilot or any crew members before the plane touched down hard and he heard a loud sound.

“We knew something was horrible wrong,” said Singh, who suffered a fractured collarbone and had his arm was in a sling.

“It’s miraculous we survived,” he said.

A visibly shaken Singh said the plane went silent before people tried to get out anyway they could. His 15-year-old son said luggage tumbled from the overhead bins The entire incident lasted about 10 seconds.

Another passenger, Benjamin Levy, 39, said it looked to him that the plane was flying too low and too close to the bay as it approached the runway. Levy, who was sitting in an emergency exit row, said he felt the pilot try to lift the jet up before it crashed, and thinks the maneuver might have saved some lives.

“Everybody was screaming. I was trying to usher them out,” he recalled of the first seconds after the landing. “I said, ‘Stay calm, stop screaming, help each other out, don’t push.'”

Hayes-White said she did not know the ages or genders of the people who died, but said they were found on “the exterior” of the plane. She said the 307 passengers and crew members had been aboard had been accounted for following several hours of confusion during which authorities said they were unsure of the whereabouts of more than 60 people who, as it turned out, had been evacuated to a different area of the airport.

Based on witness accounts in the news and video of the wreckage, Mike Barr, a former military pilot and accident investigator who teaches aviation safety at the University of Southern California, said it appeared the plane approached the runway too low and something may have caught the runway lip — the seawall at the end of the runway.

San Francisco is one of several airports around the country that border bodies of water that have walls at the end of their runways to prevent planes that overrun a runway from ending up in the water.

Since the plane was about to land, its landing gear would have already been down, Barr said. It’s possible the landing gear or the tail of the plane hit the seawall, he said. If that happened, it would effectively slam the plane into the runway, he said.

Noting that some witnesses reported hearing the plane’s engines rev up just before the crash, Barr said that would be consistent with a pilot who realized at the last minute that the plane was too low and was increasing power to the engines to try to increase altitude. Barr said he could think of no reason why a plane would come in to land that low.

Belding was out jogging just before 11:30 a.m. on a path across the water from the airport when she noticed the plane approaching the runway in a way that “just didn’t look like it was coming in quite right.”

“Then all of a sudden I saw what looked like a cloud of dirt puffing up and then there was a big bang and it kind of looked like the plane maybe bounced (as it neared the ground),” she said. “I couldn’t really tell what happened, but you saw the wings going up and (in) a weird angle.”

“Not like it was cartwheeling,” she said, but rather as though the wings were almost swaying from side to side.

The flight originated in Shanghai, China, and stopped over in Seoul, South Korea, before coming to San Francisco, airport officials said. The airline said there were 16 crew members aboard, and the 291 passengers included 77 South Koreans, 141 Chinese, 61 Americans and one Japanese citizen. The nationalities of the remaining passengers weren’t immediately known.

Airport spokesman Doug Yakel said 49 people were in serious condition and 132 had less significant injuries.

The airport closed for several hours, and when it reopened, two of the four runways were operating.

Asiana is a South Korean airline, second in size to national carrier Korean Air. It has recently tried to expand its presence in the United States, and joined the Star Alliance, which is anchored in the U.S. by United Airlines.

The 777-200 is a long-range plane from Boeing. The twin-engine aircraft is one of the world’s most popular long-distance planes, often used for flights of 12 hours or more, from one continent to another. The airline’s website says its 777s can carry between 246 to 300 passengers.

The flight was 10 hours and 23 minutes, according to FlightAware, a flight tracking service. The 777 is a smaller, wide-body jet that can travel long distances without refueling and is typically used for long flights over water.

The most notable accident involving a 777 occurred on Jan. 17, 2008 at Heathrow Airport in London. British Airways Flight 28 landed hard about 1,000 feet short of the runway and slid onto the start of the runway. The impact broke the 777-200’s landing gear. There were 47 injuries, but no fatalities.

An investigation revealed ice pellets that had formed in the fuel were clogging the fuel-oil heat exchanger, blocking fuel from reaching the plane’s engines. The Rolls-Royce Trent 800 series engines that were used on the plane were then redesigned.

Bill Waldock, an expert on aviation accident investigation, said he was reminded of the Heathrow accident as he watched video of Saturday’s crash. “Of course, there is no indication directly that’s what happened here,” he said. “That’s what the investigation is going to have to find out.”

The Asiana 777 “was right at the landing phase and for whatever reason the landing went wrong,” said Waldock, director of the Embry-Riddle Aeronautical University accident investigation laboratory in Prescott, Ariz.

“For whatever reason, they appeared to go low on approach and then the airplane pitched up suddenly to an extreme attitude, which could have been the pilots trying to keep it out of the ground,” he said.

The last time a large U.S. airline lost a plane in a fatal crash was an American Airlines Airbus A300 taking off from John F. Kennedy International Airport in New York in 2001.

Asia remains one of the fastest-growing regions for aviation in the world. Even with slowing economies in Japan and China, airlines there saw 3.7 percent more passengers than a year ago, according to the International Air Transport Association.

Finding enough experienced pilots to meet a growing number of flights is becoming a problem. A 2012 report by aircraft manufacturer Boeing said the industry would need 460,000 new commercial airline pilots in the next two decades — with 185,000 of them needed in Asia alone.

“The Asia-Pacific region continues to present the largest projected growth in pilot demand,” the report said.

“There were three crew members and 25 passengers on board,” the Interstate Aviation Committee said in a statement. “Nineteen people died, the aircraft burnt down,” said the statement, citing the surviving crew members.

Of the 25 passengers 11 were children, the emergencies ministry said in a separate statement without providing further details.

The people died when the helicopter performed a hard landing, apparently in bad weather conditions, 45 kilometres (28 miles) northwest of the small town of Deputatsky in the Yakutia region in Russia´s north.

A plane with rescuers and medics on board has arrived at the crash site, said the emergencies ministry, adding that helicopters with more medics and rescue workers have also been dispatched to the scene.

Russia´s aviation industry remains blighted by repeated accidents involving its ageing fleet of planes and helicopters.

The Taliban quickly claimed responsibility for the crash, but the coalition said in a statement to The Associated Press: “Taliban’s claims are false.”

It said the cause of the crash was being investigated by emergency crews that rushed to the site, but there was no sign of insurgent activity in the area at the time.

Capt. Luca Carniel, a coalition spokesman, said the aircraft crashed from a low altitude right after takeoff.

The coalition did not identify the victims, the type of aircraft involved, or the company that owned it.

In another development, President Hamid Karzai accused U.S. forces of killing four civilians and wounding one in the eastern province of Nangarhar on Sunday after an American’ convoy was attacked by insurgents.

In a statement issued by his office, Karzai “strongly condemned the killing of innocent civilians.”

The U.S.-led military coalition said it was still investigating the weekend clash, which left four soldiers with minor injuries and damaged a patrol vehicle. In a statement issued on Monday, the coalition said the Taliban attacked the coalition patrol with small arms fire and roadside bombs as it moved through a local bazaar in the province where there were civilians.

“Coalition forces engaged the enemy, pushed through the hostile area, and traveled to a nearby Afghan National Army checkpoint,” the coalition said in a statement. “An investigation is currently underway to assess whether there are any civilian casualties as a result of insurgent fire.”
