Oh, I do take your word for it, that is, that you believe it. But it is sad, that in this day and age, superstition runs so deep in some ideologies, that one can still doubt such things as the fact, "manned heavier than air flight is possible," is certain.
It may be of interest to you to consider, that up to the day the President Theodore Roosevelt ordered public trials by the Wright Brothers, the authorities were proving by their "logic" that manned heavier than air flight was impossible five years after the Wright brother's first successful flight.
The authorities were using logic (without experience), which, according to you is the only means to certainty, while the Wright bothers were using their experience, which, according to you is only "probable."
You must be terrified of flying.
