From Alain, the whiz kid of amazing facts & surprising statistics!.......
Where does he get them from?!

"Regarding the Vietnam war with the USA, did you know that the US boys were involved in heavy firing and life threatening shooting for a period of 240 days during their 13 month duty.

This is 6 times more than for the US Army during WW 2.

Did you also know that at any moment during the period 1965 / 1973 there were statistically at least 115 airplanes or helicopters in the air: incredible."

Incredible, indeed.
Thanks Alain!
