How John Elway travels incognito:

When he's out and about near his Denver home, former Broncos quarterback John Elway has come up with a novel way to travel incognito -- he wears his own jersey. "I do that all the time here," the 50-year-old Hall of Famer told me. "I go to the mall that way. They know it's not me because they say there's no way Elway would be wearing his own jersey in the mall. So it actually is the safest thing to do."

Rand Simberg on alternatives to rockets for space travel:

There have been plenty of alternative means of getting into space proposed over the years that don't employ traditional chemical rocket engines. The list presented here isn't exhaustive but representative, and they fall into four broad categories -- cannons, external-energy vehicles, static structures and dynamic structures.
