There were two Bills on the sqn: Sqn WO Bill xxx, a real WO, feared and respected in equal measure, and Chf Tech Bill xxx sqn eng ops. The line squawk box goes, 'is Chf Tech xyz there?' I'll find him sir, recognizing the voice. John, Bill wants you on the box. Yes mate, says John on the box, what can I do for you? Wrong Bill, the box melted as the WO explained to John the facts of life; John was mortified. I felt a little guilty so I went to the hangar and confessed to setting up poor John. I got the WO look that froze me to the spot. But, man that he was, WO Bill went over to the line hut and made peace with John. Me? I was in the dog-house only for a day or so.
