CAIRO -- Work has begun in Egypt to decode information from the flight data and cockpit voice recorders -- the so-called "black boxes" -- from the Russian jetliner that came apart in the sky and then crashed down into Egypt on Saturday, but officials caution the process will take some time, and they're urging patience.
CBS News correspondent Allen Pizzey reports the search area around the debris in Egypt's Sinai Peninsula has been widened again, now to 15 square miles.
