No news on how it happened but it's still stuck.
Thailand tends to downplay the true story on transport incidents to protect its tourist industry.
Trang airport is to remain closed until Thursday while technicians attempt to shift a Nok Air plane that skidded off the runway and became lodged in the ground in an accident on Tuesday.
Woradej Harnprasert, director-general of the Civil Aviation Department, declared on Wednesday that the airport would remain closed until at least 6am on Thursday, because the Boeing 737-800 could not be moved from the site of the accident.
Thai Airways International has sent special equipment to Trang to help move the aircraft and the operation could complete by midnight Wednesday, he said.
Authorities initially tried to use a crane from Hat Yai international airport to lift the plane from where it slid off the runway. But Trang airport director Thaworn Saengamphai said on Wednesday that the crane could not move the Boeing, because its three tyres had sunk into the ground.

Patee Sarasin, chief executive of Nok Air, said heavy rains also delayed the operation to rescue the plane.
The closure affected four Nok Air flights on Wednesday - two inbound from Don Mueang and two outbound. It also affected four Thai AirAsia flights - two from Bangkok and two from Trang.
Nok Air passengers have been diverted onto alternative flights through Nakhon Si Thammarat airport, Mr Patee said. Thai AirAsia has moved customers onto flights to and from Krabi airport, chief executive Tassapon Bijleveld said.
The accident on flight DD7411 took place while pilots were readying the Boeing 737-800 plane for takeoff at 5.45pm amid heavy rains on Tuesday.
All 142 passengers and crew on board are safe.
The passengers, many of who were foreign tourists, were moved out of the aircraft to the terminal, and transferred by bus to Hat Yai international airport for an alternative flight to Bangkok, but a number decided to cancel their trips.
Trang airport was hit by poor visibility on Tuesday due to torrential rain, which forced Nok Air's flight DD7410 from Don Mueang airport to circle above the airport for some time before making a safe landing at 4.55pm with 120 passengers on board, Mr Thaworn said.
Unfortunately, the return flight of the same aircraft was unable to take off, he added.
The accident is the second in three years at Trang airport for Nok Air. One of its aircrafts developed a problem with one of its brakes on landing on Sept 24, 2011, forcing the pilot to bring the plane to a dead stop in the middle of the runway.
