TAIPEI, Taiwan (AP) -- A Taiwanese flight carrying 58 people turned on its side in midair, clipped an elevated roadway and careened into a shallow river Wednesday shortly after taking off from Taipei, killing at least 19 people and leaving 24 missing, officials and media reports said.

More than half of the passengers aboard TransAsia Airways Flight GE235 were from China and the death toll was expected to rise as rescue crews cleared the mostly submerged fuselage in the Keelung River. Teams in rubber rafts clustered around the wreckage, several dozen meters (yards) from the shore.

Dramatic video clips apparently taken from cars on Taiwan's National Freeway No. 1 were posted online and aired by broadcasters, showing the ATR 72 prop-jet as it pivoted onto its side while zooming toward the elevated highway. In one of them, the plane rapidly fills the screen as its now-vertical wing scrapes over the road, hitting a vehicle before heading into the river.

It was the airline's second French-Italian-built ATR 72 to crash in the past year.  Wednesday's flight had taken off at 11:35 a.m. from Taipei's downtown Sungshan Airport en route to the outlying Taiwanese-controlled Kinmen islands. The pilot issued a mayday call shortly after takeoff, Taiwanese civil aviation authorities said.

TransAsia director Peter Chen said contact with the plane was lost four minutes after takeoff, but that weather conditions were suitable for flying and the cause of the accident was unknown. “Actually this aircraft in the accident was the newest model. It hadn't been used for even a year,” he told a news conference.

Thirty-one passengers were from China, Taiwan's tourism bureau said. Kinmen's airport is a common link between Taipei and China's Fujian province.

Taiwan's Civil Aeronautics Administration said 19 people were confirmed dead, 15 were injured and 24 were still missing.

Wu Jun-hong, a Taipei Fire Department official who was coordinating the rescue, said the missing people were either still in the fuselage or had been pulled down the river.

“At the moment, things don't look too optimistic,'' Wu told reporters at the scene. “Those in the front of the plane are likely to have lost their lives.”
