I think she is saying that both stupid & clever people die in private aircraft. Given the number of clever people who fly, and the nature of the environment, it is probably true that clever people die at the the same rate as stupid people. i.e. your intelligence will NOT protect you. But I think air sense will. My definition of 'air sense' is the good judgement you use in situations in the air. Such judgement will not be tested in an 'intelligence' test, which will not tend to test any kind of judgement.
So not a suprising finding then.
