Two of the most prized possessions in the Museum's collection are a pair of logbooks recording events related to the 103rd Aero Squadron from the First World War. The 103rd squadron was the first American combat squadron to see action in the War and was initially comprised of 17 pilots from the famed Lafayette Escadrille, the French squadron made up of mostly American volunteers. One of the logbooks contains a record of the flight operations of the squadron, including hours flown and a narrative about each day's activities. Some of these reports, listed as the "Nature of Patrol" are quite interesting and detailed.

The other logbook records more the Squadron's more mundane activities not related to flight, such as the names of new squadron members, or where the 103rd was stationed. This book spans the period when the squadron was formed till when it returned to the United States after the War.

The logbooks were professionally repaired and digitized in 2006. There is some speculation that the logbooks were discovered in a trashcan in Coronado by a collector. The activity logbook was transcribed in 2020 by Steve Ruffin. The logbooks and the transcription can be viewed on Archive.org
