the pleasure of the president for almost three years before continuing his service in Korea and Vietnam and at the Pentagon. President Eisenhower invited Col. Olson to join him at a White House luncheon in 1959 at which Col. Olson was required to convince the president he should be allowed to pursue his career beyond the limits of the Marine One assignment. President Eisenhower reluctantly agreed to Col. Olson's request. Because of his historic role and his long involvement with the HMX-1 Squadron and Marine One operations, the squadron's new facility at Marine Base Quantico, Va., was dedicated in honor of Col. Olson (1919–2012) on August 12, 2010. Col. Olson spoke at the dedication of the facility, a rarity for named Marine facilities throughout the world, most of which recognize deceased Marines. Shortly after the September 7, 1957, mission from Newport, a naval aide to the President asked HMX-1 to evaluate landing helicopters on the south lawn of the White House. Preliminary assessment and trial flights concluded that ample room was present for a safe landing and departure. Formal procedures were finalized and HMX-1 began a long career of flying the President of the United States to and from the South Lawn and Andrews AFB, the home of Air Force One. Col. Olson is credited with initiating many of the procedures which are now standard operating procedure, including painting the top of the otherwise Marine green helicopters white, thus their "White Top" nickname. It also was Col. Olson who conceived the placement of the large white circular target at a predetermined spot on the White House lawn for the nose of Marine One on landing, a function necessitated when the White House gardener complained to Col. Olson that the rotor craft were destroying the trees, shrubs, and flowers on the South Lawn. Initially, the helicopter function was shared with the Army, but in 1976, the Marine Corps was assigned the sole responsibility and mission of providing helicopter support to the President worldwide. Today HMX-1 also supports the Vice President, Secretary of Defense, Secretary of the Navy, Commandant of the Marine Corps, and all visiting heads of state in the Washington, D.C., area. On July 16, 2009, Marine One flew with an all-female crew for the first time, as the final flight of the first woman to fly the president: Major Jennifer Grieves.
