Captain August Thayer Iaccaci, Sr. (6 June 1893 – 30 April 1980) was a US-born World War Iflying ace who, together with his gunners, was credited with 17 aerial victories.
He scored his first victory on 19 May 1918, over a Pfalz D.III fighter; on 31 May, he became an ace with his fourth and fifth wins; coincidentally, his brother matched his feat with his fourth and fifth victories on the same day. By September, he ran his total to 11 destroyed, 5 (and 1 shared) "out of control". His score of 17 equaled his brother's. His usual observer was Sgt. Arthur Ernest Newland, an ace in his own right. With the exception of one reconnaissance two-seater, August Iaccaci triumphed over German fighter planes and pilots. He was then appointed a flight commander with No. 48 Squadron in October. Late that month, an eye wound hospitalized him in Britain for the remainder of the war.[3]
