All 163 people aboard a Caribbean Airlines jetliner survived when the plane skidded off a wet runway in Georgetown, Guyana, and split in two.

The Boeing 737 was on a flight from New York to the South American nation early Saturday when it overshot the runway and came dangerously close to a 60-meter deep ravine.

Several people were injured, some of them hospitalized.

The cause of the incident is not known. But investigators from the United States and Guyana are analyzing information from the flight data and voice recorders.

The plane had made a brief stop in Trinidad before arriving in Guyana's capital.

In the northern U.S. state of Alaska, four people died when two singe-engine planes collided in mid-air, sending one of them to the ground in a fiery crash.

Though the other plane sustained significant damage, it was able to land safely at the airport in Anchorage.

There was no immediate word on the cause of the incident. It followed a similar in-flight collision earlier in the month, survived by all 13 people aboard the two planes.
