93 Sqn convoy during a stop on the way home to Jever from Sylt - Mar55.   The message on the back of the trailer becomes clear if you reverse the letters!   Anyone name the culprits?   Ken Senar tells us that this reversed lettering appeared as graffiti almost all over everything in 93 Squadron ground crew rest rooms (and elsewhere) throughout this entire detachment - it even re-appeared after 'bull' sessions!   It was the 'in' expression at the time.   (Thanks to Peter Rose.)
