| A cargo plane has crashed on take-off from Halifax, Canada, leaving all seven crew members feared dead. The Ghana-registered MK Airlines Boeing 747 plane crashed into a quarry at the end of the runway at about 0340 local time (0740 GMT), Canadian media says. Canadian radio said a local hospital had called off its code orange alert - suggesting no survivors are expected. An MK Airlines spokesman said the crew were Zimbabwean and South African, but some reports say they included Britons. The cause of the crash is unknown. The airline spokesman told PA news agency the Sussex, UK-based company was still trying to get information about the crash and was sending a team to Nova Scotia. The news agency Associated Press reported a witness, Peter Lewis, as telling radio station CJCH he had been dropping off his wife at the airport when he saw two explosions. "As we were approaching we saw what I thought was heat lighting 'cause I told everyone in the car that we've got heat lightning in the sky," Mr Lewis said. "That was only a quick one followed by a second one that was bigger. And then we seen a very bright orange light, and I mean bright. It took up the whole sky." The plane is reported to have been carrying tractors and seafood when it crashed. |
