A military aircraft with 22 Marines on board made a hard landing during training in Hawaii on Sunday that resulted in one death and injuries to the other 21.

The aircraft, a Bell Boeing V-22 Osprey, was from the 15th Marine Expeditionary Unit and it landed in the Marine Corps Training Area around noon. A spokesman, Capt. Brian Block, said the training mission was “routine sustainment training.”

Witnesses said three aircraft were seen lowering to the ground before the incident. Shortly thereafter, black smoke began to rise and only two aircraft flew back up. "At first I thought it was clouds, but it was moving fast and it was pretty dark," Donald Gahit, who saw the smoke from his home nearby, said.

“The cause of the incident is under investigation,” Block added.

Capt. Alex Lim, another spokesman, offered condolences to all those affected by the tragedy.
