Jet nose cone caves in mid-flight

Northwest Airlines is investigating why the nose cone on one of its planes caved in on a flight Sunday from Detroit, Michigan, to Tampa, Florida.
The damage to the plane occurred during the flight, but didn't affect Flight 478's scheduled 2:30 p.m. landing in Tampa, Florida, said Northwest spokeswoman Kristin Baur.
Baur, who called the damage a "minor maintenance issue" and a "very rare occurrence" said all 182 passengers on board arrived in Tampa safely.

The Boeing 757 is one of the most common commercial aircraft in use today. The nose, which is made of a carbon fiber, houses radar that scans for weather.
