The regional airline flight in Alaska that crashed, killing all 10 people onboard, was overweight before it took off, according to a preliminary report released Wednesday by the National Transportation Safety Board.

A mid-air collision between two small aircraft near Marana Regional Airport (AVQ) on the morning of Feb. 19 left two people dead and one seriously injured.

A Cessna plane that crashed while flying to Nome, Alaska, last month, killing all 10 people on board, was hundreds of pounds too heavy for icing conditions, a National Transportation Safety Board report says.
