William Lenoir, astronaut who flew on first operational space shuttle mission, dies, Collectspace
"Former NASA astronaut William "Bill" Lenoir, who flew aboard the first operational mission of the space shuttle in November 1982, died Saturday at age 71. According to sources close to his family, Lenoir died after suffering head injuries during a bicycle accident Thursday. Lenoir, who was selected by NASA for its sixth astronaut group and second class of "scientist-astronauts" in 1967, did not fly in space until 15 years later as a member of the STS-5 crew."


Having been in a bad bicycle accident myself this summer I can easily see how this could happen. I was very lucky. I have since run into many people that have told me how bad they or a member of their family were hurt while riding a bicycle. My sympathy goes out to Bill Lenoir's family. Please be careful out there.
