Workers walk past flowers laid at the scene where the Ethiopian Airlines Boeing 737 Max 8 crashed shortly after takeoff on Sunday killing all 157 on board, near Bishoftu, or Debre Zeit, south of Addis Ababa, in Ethiopia on Wednesday. Much of the world, including the entire European Union, has grounded the Boeing jetliner involved in the Ethiopian Airlines crash or banned it from their airspace, leaving the United States as one of the few remaining operators of the plane involved in two deadly accidents in just five months.
