A Jet Airways Boeing 737 aircraft with 161 people on board veered off an airport runway in Goa shortly before take-off just before daybreak Tuesday, crossing a field before spinning into a ditch on the side of a service road. A dozen people suffered injuries as the 154 passengers and 7 crew on the Mumbai bound flight were evacuated, Jet said. Television images showed injured lying on stretchers in darkness on the service road, with fire engines parked near the stricken plane, which appeared to have lost its front undercarriage, and damaged a wing as it rested on its belly and engine casings. A Jet Airways spokeswoman said the carrier was looking into how the incident occurred. <br/>
