'Lost screws' to blame for airport leg manglingAirports of Thailand medics help an injured woman after her leg became caught in a moving walkway at Don Mueang airport on June 29. Assoc Prof Weerachai Phut-dhawong, a lecturer of the Chemistry Department at Kasetsart University's Faculty of Liberal Arts and Science, said it really was an accident. Speaking after the committee meeting on Friday, Assoc Prof Wee-rachai said the mechanical failure might have been caused by missing screws under the platform. Three screws were missing, so when she stepped on the panel, it fell while the walkway was still moving and trapped her leg. The question is how those screws went missing, he said, surmising it might be because the moving walkway was too old.
