Rebelling against political propaganda, acclaimed photographer Antanas Sutkus embarked on a life-long journey to capture the everyday scenes around him. Antanas Sutkus, born in 1939, studied journalism at Vilnius University in the late 1950s before becoming disillusioned by the confines of the Soviet-controlled press. He began taking photographs instead, and soon co-founded the Lithuanian Association of Art Photographers. Here: The first Lithuanian bikers, 1974. (Photo by Antanas Sutkus)

“NASA's Pathfinder, Pathfinder Plus, Centurion and Helios Prototype were an evolutionary series of solar- and fuel-cell-system-powered unmanned aerial vehicles. AeroVironment, Inc. developed the vehicles under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program. They were built to develop the technologies that would allow long-term, high-altitude aircraft to serve as “atmospheric satellites”, to perform atmospheric research tasks as well as serve as communications platforms”. – Wikipedia

The 18-hour flight was a functional checkout of the aircraft's systems and performance in preparation for an attempt to reach sustained flight at 100,000 feet altitude later in the summer.
