A gazelle crew from Detmold(one of whom could be called Arfur) arranged to take the wife of the Sqn OC for a famil flight. She was an air traffiker in the Detmold tower, so it was all above board. towards the end of the flight, they dropped in at a local landmark(big comms mast, the name of which escapes me), that also had a cafe, for kaffe und kuchen.
At the end of the refreshment, the good lady had to visit the little girls room and the plot was hatched. One of the crew paid the bill and departed for the aircraft. Upon the lady's return it was explained by the other that they had come flying without their wallets and couldn't pay the bill(no I don't know why she couldn't pay). When the aircraft started, they would do a runner, jump in and fly off. She was obviously aghast at this, but had to go along or be left stranded, but agreed to be sworn to secrecy.
The deed was done and they arrived back at Detmold. The crew got to the OC before she did and briefed him accordingly. He spent the evening asking various questions as to how her trip went, while she tried to avoid giving the game away.
