Planes that returned safely all have holes as marked in the diagram above. Those are the places that were shot but still allowed the plane to return safely. Some people argued that those are the places that need to be strengthened.
The part without holes in the diagram? Those planes got shot in those places and never get to make it back hence never made it into statistics. Basically survivorship bias.
