The plane crashed during the night of February 12, and exploded when it hit a home, killing all on board and one in the house.

How they unraveled the causes of the crash of Colgan Air offers insight into how the investigations are being conducted into the crashes of Major accident investigations include teams of specialists who look at particular aspects of the accident.
