U.S. Sen. Elizabeth Warren of Massachusetts is calling on the FAA to ground Boeing 737 Max 8 aircrafts until they can guarantee the planes will fly safely.
"Any necessary changes must be made before, not after, more flights occur and more lives are potentially endangered," Warren said in a statement Tuesday.
Warren cited suspicions that the aircrafts had been put out for use without necessary pilot training to save money and the decisions of other countries to halt using the airplanes.
"The Boeing 737 MAX 8 is a major driver of Boeing profits," said Warren. "Congress should hold hearings on whether an Administration that famously refused to stand up to Saudi Arabia to protect Boeing arms sales has once again put lives at risk for the same reason."
Warren's statement comes in response to a second deadly crash of a 737 Max 8 make of airplane this weekend in Ethiopia that has called into question the safety of aircraft.
