Salisbury plain, setting up the camp, and determining where to put the OP.
Pilot in charge “we will put it there”, everyone looks bewildered as it is clearly in the wrong place, then comes the immortal words from same mouth, “trust me, I have a degree in Geography”.
RAF Regt officer turns up later to survey the site and asks “Which fecking idiot decided to put the OP there”
All hands rapidly point at the said pilot.
