While walking down a country road during hot midday I observed 3 fast moving silver objects directly overhead.
Which I would now estimate to be 30,000' to 35,000' in altitude
At a speed of about 3,000 mph.
I am a licensed general aviation commercial pilot instructor and can now estimate the speed and altitude whereas I was unable to do so in 1947 at the age of 10 years old.
After the passing of the objects a hot metalic silver flake about the size of and shape of a sunflower seed appeared on my right forearm.
As the flake was apparently burning into my skin I attempted to brush it off with my left hand.
I do not know what happened to the burning hot flake, whether it dissolved, burned into my skin or was discarded.
I have never disclosed this event to anyone until today.
