http://www.msnbc.msn.com/id/25446869 Happened this evening in AZ, close to Flagstaff. In addition to the 7 dead, 3 more are critically injured. ( They may be ground ambulance crew who were on the scene when one helicopter exploded). This is so horrible. The helicopters were not recognizable as helicopters after the mid-air collision. God rest their souls and help their survivors to cope. Maria Edited because the death toll has been downgraded from 7 to 6. A flight nurse on one of the choppers survived the crash and is in critical condition. God be with her.
