What do we know about the crash that killed the pilot of a Chinese plane that crashed in the U.S.

A pilot of the Chinese J-20 fighter jet that crashed Friday in Alaska says he believes it was not a accident, but rather a terrorist attack.

The pilot, Cheng Zheng, told The Associated Press that he believes the plane was hijacked by terrorists, who were attempting to take over the plane.

He said he was not aware of any intelligence indicating that the plane had been shot down by the U and the Chinese military.

Zheng said he saw the plane’s tail “crack” and that it began to descend, but that he could not determine whether it hit the ground or exploded.

He was not immediately available for comment on Saturday.

The plane crashed at about 9:20 a.m. at an airport in Valdez, Alaska, about 90 miles (145 kilometers) north of Anchorage.

Authorities are looking into the possibility that it was intentionally shot down, or that it might have crashed during an American air show.

The U.N. Security Council is holding an emergency meeting Saturday to discuss the incident.

U.K. Foreign Secretary Boris Johnson, who is also on the U, China, Russia and Eurasia committees, said the United States has “an obligation to stand up for our allies and the international order.”

The plane had crashed during a test flight in March and was carrying a Chinese pilot and a Russian pilot, according to the Associated Press.
