A twin-engine plane crashed and burst into flames while landing tuesday, killing all four people on board, the Federal Aviation Administration said acording to The Associated Press. No one on the ground was hurt when the jet-engined Cessna 560 was landing at McClellan-Palomar Airport on a flight from Hailey, Idaho, when it skidded off the end of a runway early Tuesday morning, said Mike Fergus, a Federal Aviation Administration spokesman in Seattle. It hit a shack that held the airport's instrument landing system equipment, Fergus said. «All four on board were killed,» he said. The airport 30 miles (48 kilometers) north of San Diego was closed. --SP 20 50 Local Time 17 50 GMT
