Jet dives to avoid another plane; 4 are hurt

At least four people were injured Tuesday when the crew of an American Airlines MD-80 took evasive action to avoid at least one other plane in the airspace just west of Tulsa, Okla.

There were 90 people on board American Airlines flight 490 from Oklahoma City to St. Louis when the plane's collision avoidance system warned of heavy traffic in the area and then ordered the crew to descend immediately, airline officials said.
