Defense Secretary Pete Hegseth did not appear at the Thursday morning press conference. He was expected to brief reporters at the Pentagon later.
If everyone aboard the plane was killed, it will make it the deadliest U.S. airline crash since Nov. 12, 2001, when an American Airlines flight just after takeoff crashed into a residential area of Belle Harbor, New York, killing all 260 people aboard.
The last major fatal crash involving a U.S. commercial airline occurred in 2009 near Buffalo, New York. Everyone aboard the Bombardier DHC-8 propeller plane was killed, including 45 passengers, two pilots and two flight attendants. Another person on the ground also died, bringing the total death toll to 50. An investigation determined that the captain accidentally caused the plane to stall as it approached the airport in Buffalo.
