I find it difficult to determine the definition of "dangerous" in the context of "flying".
If you ride a motorcycle /pushbike /drive a car / walk etc, you are in very close proximity to others doing the same in conflicting directions. (please remember the "very close" part.
If you fly a light a/c you are not, "in spite of the "crowded skies" lobby".
Therefore you are more in control of your own destiny when flying than you are when on the ground.
If YOU choose to fly in a thunderstorm, fly a single engine a/c (piston) over water for long distances, over mountains in high winds etc, then YOU are placing yourself in a situation that YOU may not be able to control all the way to it's conclusion.
On the othe hand you may have little choice but to drive to work in a snowstorm within inches of numerous, perhaps less competent, persons.
Therefore it's far more dangerous to be on the ground standing at a bus stop than at 5000ft strapped into anything.
Statistics are just numbers that naysayers use.
Most people in the developed world die in bed.
Most people in the developed world die when they are old.
Most people in the developed world die having drawn a pension.
Solution: Don't join a pension scheme, spend all your money on an a/c while you are young, instead of sleeping, fly it at night, low so you can see the ground, slowly to give yourself time to avoid things. This will ensure you do not get old, therefore you should not die.
