An Indonesian jetliner crashed into a crowded residential neighborhood in the city of Medan shortly after takeoff Monday, killing all 117 on board and an unknown number on the ground, officials said. The Mandala Airlines Boeing 737 was heading to Jakarta when it crashed one minute after takeoff and burst into flames, said Transport Minister Hatta Radjasa. It was carrying at least 117 passengers and crew, said the airline's acting president, Maj. Gen. Hasril Hamzah Tanjung. "They have all died," Edi Sofyan, a government spokesman in Medan, told The Associated Press by telephone. There were also casualties on the ground, he said, though he did not know how many.
