At least two people were killed when a small medical transport plane crashed early Friday in remote Northern California, the Los Angeles Times reports. The plane was carrying a pilot, patient, transport medic, and flight nurse. Officials did not give any information on the conditions of the other two passengers. The plane's wreckage was found on private timber land in Humboldt County. According to NBC News, the REACH Air Medical Services plane was flying from Crescent City to Oakland when the pilot radioed around 1am local time about smoke in the cockpit. He said they were returning to Crescent City, but the plane disappeared somewhere over Arcata. (More plane crash stories.)
