The final issue for 2021 has begun appearing in mailboxes. The issue opens with a rare look at a Hungarian pilot with Oberleutnant Franz Čík of the Austro-Hungarian kaiserliche und königliche Luftfahrtruppen by Juraj Červenka. Issue Editor Mike O’Neal continues his examination of American training casualties at Issoudun, for the period May through August 1918. Lee Corbin looks at a surviving U. S. Navy seaplane hangar, still in use today albeit in a new role, in Fly Boys and Boat Boys. Greg VanWyngarden taps Charley Gosse, Charles Thomas and Mike O’Neal for assistance in Alan’s Albatros, which draws on a newly uncovered photo to provide some sidelights on the day. Russell Smith’s cover painting captures the event. In Tangible Links Charlie Walthall and Ted Huscher examine a war souvenir made from an Austrian propeller. Finally, Peter Kilduff reviews books of note in Between the Bookends.
