One Marine was killed and 21 other people were injured when a Marine Corps aircraft made a hard landing during a training exercise in Hawaii on Sunday, the Marine Corps said in a statement.

They were flying aboard an MV-22 Osprey when it experienced a “hard-landing mishap” at around 11:40 a.m. at Bellows Air Force Station on the island of Oahu, according to the statement.

Pictures posted to social media by local residents show a column of thick black smoke rising against a gray sky and emergency personnel rushing to the scene.

Capt. Brian Block, a Marine Corps spokesman, said that 22 people were aboard the aircraft, including 21 Marines and one Naval officer, according to The Associated Press.
