A Chinese man needed to be restrained after he tried to open the emergency exit thinking it was the toilet door during a flight to Hong Kong, an airline said Friday. Crew of the Hong Kong Airlines flight from Bali, Indonesia, were shocked to see the 52-year-old man rise from his seat halfway through the journey and start pulling on the emergency door handle, the airline said. The door failed to open and crew stepped in to physically restrain the man, who was identified only by his surname Peng. \"When the police questioned him after landing, he said he thought it was the toilet door, since this was the first time he had traveled on an aircraft,\" an airline spokeswoman said. The company issued the man a warning letter but police are not pursuing the case, she said.
