On September 21-22, 1935 Felix Waitkus (Feliksas Vaitkus), a reserve Air Force lieutenant, flew non-stop across the Atlantic Ocean from New York to Ireland in a Lockheed L5B, Vega christened Lituanica II. His goal had been Kaunas, Lithuania, but weather conditions prevented achieving that end. However, he did become the sixth pilot to fly solo across the Atlantic.
     The stamp was issued by Lithuania in 1936 to celebrate Waitkus’ solo flight.
