Two Luftwaffe Instructors with Their Charges During Training

Two Luftwaffe instructors with their charges during initial training. The recruits are wearing white denim clothing, which was popular both on land and for general work aboard ships. The trucks on which they are sitting were quite common at the time. They were used on building sites, quarries and other places where heavy loads had to be moved. The tracks were often laid temporarily along the roads to overcome the problem of carrying heavy loads over soft ground or rough cobblestones. Heavy loads were still moved by horses and carts until some time after World War II. Lorries composed only a tiny fraction of the traffic on roads, many of which were unsurfaced tracks - even the more busy highways were covered with bumpy cobblestones. The vast majority of modern, tarmac surfaces did not appear on the continent of Europe until long after the war.
