AHMEDABAD: "I will kill myself and the all people onboard!" Panic seized the Jet Airways Mumbai-Ahmedabad noon flight passengers on Tuesday as a man threatened to break the window of the aircraft and open the door at the height of several thousand feet. Later identified as 30-year-old Hardik Trivedi, the frenzied man attacked an airhostess before being overpowered by the fellow passengers. Before Trivedi actually attempted to open the door, he created a ruckus and bit an airhostess, who was trying to calm him down. He started running in the aisle of the aircraft like a man possessed, threatening to kill all. Scared but fellow passengers overpowered Trivedi and bashed him into submission even before the cabin crew could initiate measures to bring the situation under control. In the fisticuff with the passengers, Trivedi tore his passport in a lame attempt to protect his identity. On his way back from Muscat, Trivedi later said that he was angry as he was duped and had lost his job there. On the request of the cabin crew, a doctor, who happened to be on the same flight, injected Trivedi with tranquilizers to calm him down. "He seems to be suffering from severe depression ," the doctor who treated him in flight told the TOI correspondent who was also onboard. The cabin crew had to alert the medical and police staff for assistance before landing. From airport, Trivedi was taken to Apollo Hospital for brief treatment. As requested by the crew, police were present at the Ahmedabad airport when the aircraft landed here, however it was decided not to file an FIR as Trivedi was obviously suffering from a severe mental set-back, officials said.
