Report details wreckage of fatal New Mexico helicopter crash

ALBUQUERQUE, N.M. (AP) — Federal transportation authorities say a helicopter that was returning home from a firefighting mission made a rapid descent before plowing into the ground last month, killing the four first responders on board. Investigators with the National Transportation Safety Board released their preliminary report Friday. It noted that two witnesses on a ridge about half a mile away saw the Bernalillo County Sheriff's Office helicopter go down without making any turns. It could take a year or more to determine the cause of the July 16 crash. The report also noted that the main wreckage was found upside down about 160 feet beyond the area where the helicopter first crashed.
