New details on plane that skidded off runway in Jacksonville

JACKSONVILLE, Fla. (FOX 35 ORLANDO) - A chartered jet carrying 143 people from the U.S. military base in Cuba tried to land in a thunderstorm and ended up in the river at Naval Air Station Jacksonville on Friday night. 

Everyone on board was alive and accounted for, the Jacksonville Sheriff’s Office said, with 21 adults transported to local hospitals in good condition.

Officials gave an update on Sunday. The National Transportation and Safety Board said the plane's flight data box was recovered. Preliminary data shows the plane touched down 178 knots, that's roughly 205  miles per hour. Officials say they're looking into whether speed was a factor in the crash.

Strong thunderstorms were moving through the area during the incident on Friday,

Officials say the pilot was actually requested to change landing direction.

Investigators say the plane's thrust reversers were not working. They help slow down the plane.

Officials say the aircraft was in good shape and they're confident they will be able to recover the plane's voice recorder.

Navy divers said they recovered three pets that were on board. They were cremated.

The Associated Press reported that a passenger on the chartered jet that crashed into a river at a military base in Florida said passengers initially were told the aircraft might not be fit for takeoff. Then the flight was cleared to leave Cuba, but with the warning there would be no air conditioning.
