Arizona: Six killed in mid-air collision between helicopters

Two medical helicopters collided yesterday afternoon about a half mile from a northern Arizona hospital, killing at least six people and critically injuring a nurse, a federal official said.

After the collision, the helicopters crashed in a wooded area east of Flagstaff Medical Centre and started a 10-acre brush fire that authorities were able to extinguish, said Coconino County sheriff’s spokesman Gerry Blair.
