Mosquito Helicopters Resume Flights After Crash

MINNEAPOLIS (WCCO) -- The Metropolitan Mosquito Control District resumed flights Tuesday, the first time since a pilot working for them was killed in a helicopter crash last week.

The National Transportation Safety Board also released a preliminary report about the crash. Witnesses say they saw the helicopter lose altitude and roll to the left just before going down.

A GPS system was recovered from the crash and will be examined for more information.

The Metropolitan Mosquito Control District have already treated 100,000 acres and have identified 25,000 to 30,000 more acres that need to be treated.

In recent years, they've treated 150,000 to 200,000 acres total.
