Some people cannot read. I was in an area where we would winch personnel onto tankers. The winching area was marked with a big 'W'. One steely eyed pilot with another operator saw that the area around it was clear so he landed on to save time, all six tonnes of it.
The deck wasn't stressed for that so the ship had to go into the dockyard for a structural check.
Our company were flying that contract a few weeks later.
