Ho King-him, 27, was working in the front of a stationary tour bus when a helicopter crashed into the front of the vehicle in Kai Tak yesterday. He had a lucky escape, suffering minor cuts to the left side of his face, and right shoulder and leg as he squatted down and covered his head with his hands. Mr Ho, a mechanic, had boarded the China Travel Service bus to conduct a routine inspection for about a minute. He had noted down the odometer reading of the bus and was just about to leave, he said, when 'I saw the helicopter coming in front of the vehicle. I dodged but was hit by flying glass fragments'. He added: 'I was near the driver's seat at the time of the incident. I had no chance to escape.' He was treated at Queen Elizabeth Hospital and left at about 12.30pm. He said he was very lucky to have escaped serious injuries and thanked God. Mr Ho was afraid there would be an explosion and ran out of the coach through an emergency exit, according to his supervisor. 'He is shocked by the incident and needs time to calm down,' the supervisor said. Mr Ho has worked at the company for about a year. Some of the China Travel Service buses park in the car park and he goes round for inspections every morning before they are driven out. According to a witness, the helicopter was trying to perform a stunt but failed. The aircraft was flying at two to three storeys above ground level when it did a '180-degree turn' and went upwards, said Pannu George, a member of Cathay Pacific's ground staff who lives at Sky Tower in Sung Wong Toi Road and observed the scene from his balcony. The turn was quick and Mr George described it as a 'very good stunt'. The chopper headed towards the Aviation Club - and then lost control. 'It was spinning very fast ... for more than 10 times' before it crashed into the tour coach, he said. 'People were running away from the helicopter ... they were construction workers ... there were at least 10 people.' A construction worker surnamed Ng who took part in the rescue said he was worried the helicopter would crash into his office. He said the helicopter had swayed unsteadily when it was five to six storeys from the ground. After it crashed, Mr Ng and about six others rushed to the rescue carrying a wooden ladder. Pilot Ng Shu-keung and his son, Ng Yu-hin, were trapped in the helicopter when they arrived at the scene, the rescuer said. The son was crying and in shock, he said.
