National Transportation Safety Board releases preliminary report on loss of aircraft that killed all 10 onboard

A commuter plane that crashed on sea ice off Alaska, killing all 10 people onboard, was half a ton overweight for the weather conditions, the National Transportation Safety Board said in a preliminary report released on Wednesday.

The report said the plane was too heavy for conditions that cause icing at the speed and altitude it was flying.
