I can go better than waiting in the airfield caravan......I, and some other staff cadets used to sleep in the dam thing. We used the aldis lamps of a night time. Duty instructor the next day always wondered why the battery was flat ! Then we progressed to the Airman's transit accommodation. Mentioned our discomfort one day to the Station Warrant Officer. (Behind the back of the Gliding School CO of course. Flt Lt Bill Grey) He never found out. Honest !!!
