There are no atheists on a falling plane?

This statement is false. There is no evidence to suggest that atheists are any more or less likely to pray or ask for divine help during a crisis than any other group of people. In fact, research has found that atheists are just as likely as believers to turn to prayer in times of distress.

Furthermore, it is impossible to know the religious beliefs of all passengers on a plane, so it is impossible to say definitively whether or not there are any atheists on a particular plane. Ultimately, the statement that "there are no atheists on a falling plane" is a baseless assumption and is not supported by any scientific evidence.
