I was once B**locked, whilst at ALM grounschool at Finningley, for delivering an ID briefing at station morning prayers on the BTR70 armoured car in the style of a used car salesman....most of the Nav/NCA studes enjoyed it, but the old hairys didn't.
I have spiced up subsequent presentations using various film clips, mickey takes and flying an RC Helicopter over the audience.....
I have also fallen over on entering the room losing my entire slide deck, and then pulled out a spare deck, to start a Disaster Recovery briefing
