DURANGO — Authorities say two people were killed when the vintage plane they were in crashed in Durango.

The P-51 Mustang was taking off at the Durango-La Plata County Airport when it crashed at about 9:30 a.m. Friday. Sheriff's spokesman Dan Bender tells The Durango Herald (http://bit.ly/VLHwWp ) he did not know where the plane was headed or what went wrong.

The two who were killed were the only ones in the plane. Their names have not been released.

Bender says investigators are taking photos of the wreckage and keeping the scene secure until the National Transportation Safety Board arrives from Denver later Friday.

Before Friday's crash, there were only 123 P-51 Mustangs in the United States, according to the Federal Aviation Administration registry.
