A row of primary training gliders, marked with Nazi-era insignia, stands ready for launch at a German gliding school hillside during the 1930s. Programs like these, run under organizations such as the Deutscher Luftsportverband, trained thousands of young Germans in basic flight skills, technically circumventing the Treaty of Versailles' ban on German military aviation and helping build a reserve of future Luftwaffe pilots ahead of World War II.
