"a href="http://www.jsc.nasa.gov/Bios/htmlbios/shepard-alan.html">Alan Shepard. May 5th 1961, in the Freedom 7th Spacecraft he bacame the first American in space. You know it's always Glenn this and that, but by golly this one did it, he actually did it.... to be the First American Man In Space and... AND during Apollo 14 actually walked on the moon and brought back samples. Ask Glenn if he did that. Unfortunately, for most Americans nowadays... ask them too.
