Searchers found the smashed remnants of a small plane that vanished two days ago in a densely wooded area of southwestern Colorado. None of the nine people aboard survived when the plane went down at about an 80-degree angle, Montrose County officials said. The Cessna 208 had disappeared from radar shortly after it took off Wednesday for a 90-minute flight to Arizona. The plane was found about 17 miles southwest of the Montrose Regional Airport, on the rugged Uncompahgre Plateau. On board were the pilot and eight federal Bureau of Reclamation employees headed for a meeting at Glen Canyon dam. The bureau oversees federal dams and other water projects. Pilot Robert Armstrong had been flying with Scenic Airline for 10 years, an airline spokeswoman said.
