No Distress Call Made From Plane Before Crash

More is being learned about a deadly plane crash.  Federal investigators say the cockpit voice recorder was not working during the plane crash in Oklahoma City last week.

No distress calls were made before the small plane went down.  It had just taken off from the Wiley Post Airport.  All five men on board died in the crash.

Witnesses reported seeing a flock of birds near the plane.  The National Transportation Safety Board is investigating whether a bird was sucked into an engine.
