A chartered plane carrying five Maui County employees crashed, sparking a brush fire in an old pineapple field on Lanai Wednesday night, killing three people and injuring three others. Maui County officials say the three people killed were the pilot and two Department of Planning employees who had been on the island for a Lanai Planning Commission Meeting. Two other planning employees were in critical condition and a deputy attorney for the Corporation Counsel was in serious condition. They were all flown to Honolulu for treatment of burns and other injuries. The National Transportation Safety Board and the Federal Aviation Administration are investigating the cause of the crash.
