I once sailed from Colombia to Panama with an Italian who told me he used to transport drugs in buoys on his boat because if his boat was ever boarded by police, he could either dump the buoys or hang them over the side to protect the sides of the boats when the police pulled up alongside and boarded. He assured me at the time that he was retired from the import-export business.

And, yes, I know helicopters can’t fly as fast as a plane, but I’ve only ever seen police helicopters rather than planes, and I ran out of room to draw anything else besides helicopters.
