STEAMBOAT SPRINGS, Colo. (AP) - The National Transportation Safety Board has issued its reports on the probable causes of two deadly plane crashes that occurred in Routt County last year.
According to Steamboat Today, federal investigators say a crash at Yampa Valley Regional Airport in Hayden likely was caused by snowy weather.
That crash killed two people and seriously injured four.
In a second crash, a pilot was killed north of Milner while flying impaired by alcohol and marijuana.
