McClintock was originally a second lieutenant in the West Lancashire Brigade before transferring to the Royal Flying Corps. He began as an observer gunner in 2 Squadron in December 1915. He then became a pilot. In July 1917, he was posted to 64 Squadron as a flight commander. He drove down an LVG reconnaissance on 18 March 1918. He followed this up by destroying two German fighters on 23 March, another recon plane on the 24th, and an Albatros D.V on 2 April. He took command of 3 Squadron later that month.
