Read about the Army sharing Presidential lift responsibilities in a WSJ piece in the Early Bird. Didn't realize that, but it's true as stated in HMX-1 Official History:
Realizing the urgent need for his presence in Washington, President Eisenhower directed his staff to find a faster way to Air Force One. As luck would have it, an HMX-1 UH-34 helicopter was on Rhode Island in case of an emergency and could be used to fly the President to his awaiting aircraft. President Eisenhower approved the idea, and after the 7-minute flight a precedent was set.
Shortly thereafter, 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.
Initially this function was shared with the Army. In 1966, 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 States in the Washington, D.C. area.
