Lieutenant Geiger arrived in Oahu with two Curtiss Aeroplane Companyseaplanes, a mechanic, 12 enlisted men, and other equipment.[3] However, Geiger's aircraft were in poor shape. His flights were limited to short flights in Pearl Harbor and a longer flight to Diamond Head, Hawaii, and back to Fort Kamehameha.
Geiger was ordered to cease all flying operations in late 1913 because the trade winds were too strong.[4] The airplanes were sold locally, and the engines were sent back to the North Island Flying School. The Hawaiian Islands would not see any more Army aviation activity until 1917.
Balloons and dirigibles
Geiger completed courses at the U.S. Army Balloon School in April 1917, and later during World War I served overseas with the Army's Balloon Section Headquarters in France as a lieutenant colonel. He completed dirigible studies in France and Italy. He was attached later to the Ambassador's staff in Berlin. While in Germany, Major Geiger sent reports to the Chief of the United States Army Air Service on the construction of the dirigible USS Los Angeles, and repeatedly urged that the craft, which was later taken over by the Navy, be purchased by the Army. He was on the Los Angeles on its transatlantic flight.[1]
Geiger also commanded the Army Balloon School at Ross Field, Arcadia, California.[5] By 1927, Geiger was commandant of Phillips Air Field at Aberdeen, Maryland.
On May 10, 1926, Major Geiger was slightly injured in a mid-air collision between two airplanes at Langley Field, near Hampton, Virginia. While attending the Air Corps Tactical School at Langley Field, his airplane and another flown by fellow student Horace Meek Hickam hit each other and crashed.[6]
Death
On May 17, 1927, Geiger died in the crash of an Airco DH.4 he was piloting as he was taking off for a flight to Aberdeen Proving Grounds, Maryland.[7] A newspaper article reported six mechanics and officers at the Middleton Air Station, at Olmsted Field, Pennsylvania as saying that Geiger's airplane dove into the ground from a height of 50 feet (15 m). Geiger managed to jump out just as the airplane struck the ground and burst into flames. He made desperate efforts to get clear of the wreckage and, according to the onlookers, half crawled and ran as far as the tail of the machine before he was overcome. There he dropped and the flames prevented the watchers from getting near enough to rescue him.[1][8] Major Geiger was buried at Arlington National Cemetery.[9]
