Guess they can't teach you this sort of skill when you learn broadcast journalism.  A Fox reporter was outside the Whitney Houston Academy in  East Orange, when a crash occurs right in the middle of the live shot. Watch the reporter's face as he is being asked a question from the hosts regarding Whitney Houston's upcoming funeral when the crash occurs behind him. After a quick noticeable facial change, he quickly composes himself and moves on.

Now that's what you call a true broadcast professional!
