Formed in Texas as an observer squadron in 1917, the famed 90th was sent to France and initially assigned to build roads and barracks! The fliers didn't have to live with their disappointment for long. Composed of a remarkable cross-section of American youth, they soon found themselves in the thick of the fighting in the skies above WWI France. Several pilots were cited for distinction and, of course, the squadron lost friends to combat. This lively and well-written short history of the 90th Aero Squadron provides the background to a group that would go on to have a rich legacy in other fields of conflict.
