OCTOBER 25--Navy ships and helicopters began departing from Port Au Prince after nearly 2 weeks of relief operations in Haiti, laid waste by hurricane Flora. Four Navy ships, including the carrier Lake Champlain and the amphibious assault ship Thetis Bay, aided by Navy and Marine Corps cargo aircraft from east coast stations, delivered nearly 375 tons of food, clothing and medical supplies donated by relief agencies, and provided other assistance to the stricken populace.
