Émissions télévisées autres que de fiction.
1 online resource (Streaming video (29 min.).).
From the U.S. Army's The Big Picture television series, 1950-1975.
"Above the battlefields of World War II, the simple Piper Cub aircraft served as an observation platform for the adjustment of artillery fire, and the concept of Army Aviation as part of the ground combat team was born. Since then, the aircraft which help the fighting man do his job have become more sophisticated, more rugged, and more powerful. "Wings at the Tree Tops" have given the soldier a dimension of mobility which his foot-slogging brothers of twenty years ago would have found unbelievable."--Wdtvlive42.
