Just as a point of interest, on all our spotting trips (all european) my son always carrys a scanner (with batteries removed until destination reached).Only once has a problem occured,a few years ago departing from SXF a custom official decided he was going to confiscate the scanner i pointed out we had no batteries. After considerable disscusion,he evetually took 14 year old son to crew room (without me)and one of the front seat drivers apparently agreed to carry the damn thing and return same at BRS,as we boarded son was re-united with scanner,and afforded a cockpit tour,me,i was left to find some seats!!!
