The Trager-Bierens T-3 Alibi is an American high-wing, V-tailed, single seat glider that was designed and constructed by Kempes Trager and John Bierens.
[1][2] Using the wood and fabric LK-10 wings, Trager and Bierens built a new-design fuselage from aluminium.
The fuselage included a V-tail and a retractable monowheel landing gear.
The designers spent a lot of effort getting the wing surface smooth, which paid off later in contest results.
The aircraft was then owned by a syndicate called Alibi Flyers which remained the registered owners in June 2011.
