The wreckage of a Pan American Airways plane that crashed off Puerto Rico in 1952 has been found 74 years later. Here's what happened in the historic plane crash that changed aviation safety.

A pilot suffering a medical emergency, a plane forced down in Alaska and passenger jets nearly colliding in Boston are the latest aviation incidents under investigation as the busy summer air travel season gets underway.

Authorities say a pilot and 11 others were killed when a plane taking people on a skydiving outing in Missouri crashed in a field and caught fire.
