During World War II, the air forces of the United States and Britain bombed Germany and suffered heavy losses. Experts found that the belly of all the returning planes was covered with bullet marks, but the wings were intact. They concluded that the belly of the plane is very vulnerable to gunfire and that the protection of the belly should be improved. It was later confirmed that they were affected by survivor bias when these experts speculated, because the reality was that all the planes that were hit on the wing crashed, while most of the planes that were only hit in the belly returned.
In a random sampling survey with a large enough sample, it is found that in China, the TV program with the largest audience is News Network does not have a similar survivor bias.
