Sadly no mention of the Montgolfier brothers, who really opened up the sky to a lot of people's imagination back in the 18th century. Manned flight at 900m in 1784!
They forgot Apollo 13. (<a href="http://en.wikipedia.org/wiki/Apollo_13#Mission_notes" rel="nofollow">http://en.wikipedia.org/wiki/Apollo_13#Mission_notes</a>)
