One wet day in Germany I was lifting an 8 ton load with a Chinook from beside a small country road; a motor cyclist (on a small machine) ignored the stop signs, personnel trying to get him to stop and drove straight past. Needless to say my downwash was considerably stronger than his self belief, and the full ditch alongside the road received him, his motor bike and girlfriend riding pillion. He also blamed the helicopter - the police didn't!
