The 2008 Kenosha helicopter crash was an accident in which a helicopter crashed into a house in Kenosha, Wisconsin, killing the two people on the helicopter. The helicopter crashed into the house's roof at about 05:30 in the morning on September 21, 2008. A family of five living in the house was uninjured. The helicopter crashed through the roof of the house on its side; the momentum of its rotor blades caused it to roll down an interior staircase between occupied bedrooms before it burst into flames and came to rest on the lawn of a neighboring house. Witnesses heard the helicopter's engine sputtering before it crashed; the helicopter was flying at an altitude of approximately 500 feet, through fog so thick its lights could not be seen from the ground. The National Transportation Safety Board responded to a string of helicopter crashes including the Kenosha event with a set of hearings, beginning February 3, 2009, intended to build support for wide-ranging increases in helicopter safety regulations.
