Plane crashes in US state of Florida

Emergency crews on Sunday afternoon responded to the scene of a plane crash in Greenacres, a city in Palm Beach County, Florida, United States.

The Palm Beach County Sheriff's Office, in a statement, said the incident occurred in the area of Military Trail, between Cresthaven Boulevard and 10th Avenue North.

All northbound and southbound lanes of Military Trail are currently closed until further notice, with motorists advised to avoid the area and seek alternate routes.

Videos online show the aircraft taking a sharp turn before nosediving into the ground near a mobile home park, demolishing one trailer in a huge fireball.

Information from ADS-B Exchange website shows the plane descended 27,000 feet in the course of one minute, before flight tracking data cut off.

There are reports of "several fatalities," although the figure is still unconfirmed. It is also not yet clear whether anyone on the ground was killed or injured.

The aircraft, a Learjet 60, had departed Austin-Bergstrom International Airport in Texas and was heading to North Eleuthera Airport in the Bahamas.

Learjet 60, a business jet manufactured by Bombardier Aerospace, is typically configured to accommodate six to seven passengers alongside a two-person crew.

The Federal Aviation Administration and the National Transportation Safety Board will investigate the crash, according to the FAA.
