RENO, Nev. (AP) - A twin-engine plane on a cloud-seeding mission crashed just after takeoff Monday, killing all three people aboard. An engine on the Navy surplus plane failed after the aircraft left Stead Airport, said John Doherty, a spokesman for the University of Nevada's Desert Research Institute. The institute had contracted for the use of the plane with Advanced Aviation of Reno for a cloud-seeding mission in the Sierra Nevada south of Lake Tahoe. The institute seeds clouds during storms to increase snowfall and build water supplies for summer. The names of the victims were not immediately released. Doherty said they were Advanced Aviation employees, not with the research institute. The Federal Aviation Administration was sent to investigate.
