Before it was converted from an HH-53, the MH-53M (serial number 68-10357) on display took part in the Son Tay Raid -- one of the most famous combat actions of the Southeast Asia War. Flown by Lt. Col. Warner A. Britton under the callsign "Apple 1," it carried the mission's "command element" on the mission to rescue American prisoners of war thought to be held at the Son Tay prison near Hanoi, North Vietnam.
