Fifty-five containers presumably containing the remains of service members killed in Korea in the early 1950s arrived in Honolulu on military planes Wednesday, weeks after President Donald Trump received a commitment from North Korean leader Kim Jong Un for their return.

Each container was accompanied by one U.S. Marine, one sailor, one soldier and one airman. Some of the remains could be of military personnel from other countries that fought alongside the U.S. in the war.

Inside a hangar at Joint Base Pearl Harbor-Hickam, invited guests awaited the procession of the fallen.

Vice President Mike Pence spoke at the ceremony, saying,”Some have called the Korean War the ‘forgotten war.’ But today, we prove these heroes were never forgotten. Today, our boys are coming home.”

The guests included service members who saluted their fallen comrades.

The remains were flown to Hawaii in military planes from South Korea. What is expected to be an exhaustive analysis and identification process will soon begin.

There are 7,699 U.S. service members listed as unaccounted for from the 1950-53 Korean War, of which about 5,300 are believed to have died on North Korean soil.
