In the wake of two airline crashes and an emergency landing involving the Boeing 737 MAX plane, the U.S. Department of Transportation (DOT) has established what it says is an expert Special Committee to review the Federal Aviation Administration’s (FAA) procedures for certifying new aircraft.

A March 10, 2018 crash involving an Ethiopian Airlines flight claimed the lives of all 157 people aboard. The October 29 crash of a Lion Air plane into the Java Sea off Indonesia killed its 189 passengers and crew. Both incidents occurred shortly after takeoff, as did the emergency landing that occurred on Tuesday at Orlando International Airport. The Florida incident, which involved a Southwest Airlines flight, had no fatalities.
