the missing "a"
There is a prograph.

"An Australian computer programmer says he found the missing "a" from Armstrong's famous first words from the moon in 1969 ,when the world heard the phrase ,"That's one small step for man ,one giant leap for mankind."

Did the computer programmer found the "a" from the phrase ?
or the prograph means that the computer programmer actually didn't find the "a" .

I thought it maybe a stupit question ...but i was really confused . According to the hole article, the computer programmer didn't find the "a"...

Answer

"Found" as in "identified and proved its existence".  The whole article doesn't go into too much detail, but basically the phrases "for (a?) man" and "for mankind" were compared and there was evidence of the missing "a".
