Somebody Call Tom Clancy - Yes, it's like the plot of a bad action movie, but the U.S. government is worried about a jetliner gone missing over Africa. The fear is, now that commerical airline security is tighter, that terrorists will obtain a human-piloted missle by sneakier means. Strangely, this story was noted on ABC's World News Tonight weeks ago (I saw it from the treadmill at the gym) but wasn't widely repeated at that time. I guess the continuing absence of the jet has raised the story's profile. Then again, things go missing in Angola all the time, apparently.
