Ben Bloggs is ordered to fly by secret plane to France where he is given the instructions to infiltrate a German fortification and learn its physical specifications. Dumbfounded as to how he would do such a thing, he is told in jest he should just walk right up and ask. So he does. And succeeds, to his astonishment. Of course, being dressed like a Gestapo agent does help sometimes.
