"From our orbital vantage point,
we observe an earth without borders,
full of peace, beauty and magnificence,
and we pray that humanity as a whole
can imagine a borderless world as we
see it and strive to live as one in peace."
- Willie C. McCool, January 29, 2003, pilot of STS-107 (Columbia's last flight, just days before re-entry)
