Said Mr. Churchill on June 19th, 1940, "The enemy is crafty, cunning and full of novel treacheries and strategies." Parachutists – once airily discounted as on offensive arm – have already proved their deadly efficiency. But little has yet been heard of another ingenious Nazi air weapon – the troop – carrying glider train, reported to have been tried out in secret during the invasion of the Low Countries. How this stealthy and speedily reinforced method of attack would work is shown on page 604, Volume 2, an essential to its use on a large scale being hundreds of trained glider pilots. Germany, ever methodical, has provided them by sponsoring gliding as a sport in pre – war years, and in the exclusive photographs in these 2 pages, taken as late as August 1939 we see how the potential invaders were trained.
