Three people in a jet and three on the ground died during a fiery crash in 2014 that the National Transportation Safety Board (NTSB) says was caused by the pilot’s failure to turn on de-icing equipment.
The jet crashed into a neighborhood in Gaithersburg, Maryland on Dec. 8 after an accumulation of ice on the wings sent it into an aerodynamic stall. In addition to the fatalities, three houses were damaged by the ensuing fire.
