1st American in space.
He flew 116 miles high.
The entire flight lasted about 15 ½ minutes.

10 years later he would walk on the moon.
Not the first. X-15 pilots flew over 100 miles high and had to use reaction jets to correct aircraft alignment.
The Redstone launch was still a great achievement. I remember listening to it on the radio at school in the 7th grade.
That was incredible technology development in 10 years!
