A fire truck destroyed by fire. It started in the engine and quickly consumed the rig after the crew returned from a run in Highland Park earlier this month. The city has three fire trucks to cover city limits that stretch less than 3 square miles. But one fire would change that - as they were leaving a scene a likely mechanical problem sidelined their 100-foot ladder truck. Then this happened. "Once we opened the doors and it got oxygen it started fueling itself and then got on the radio and called for help," said Fire Chief Kevin Coney said. 'But the truck was totally engulfed." Being down a truck is a big blow for the department - especially since a new one costs at least $1 million a lofty price tag for a department who just last year gained a third engine.
