(CNN) - The grueling search continues for a passenger plane that disappeared on its way from Indonesia to Singapore with 162 people on board - 18 of them children, including one infant.

CNN's Tom Foreman joins "The Lead" from the magic wall to show just how investigators are sorting out what went wrong.
