The extent of injuries is still not clear after a business jet carrying eight people crashed on takeoff at the Bangor Airport Sunday night.

The airport has been closed since the crash at about 7:45 pm involving a Bombardier Challenger 650, which is a small business jet.

The city of Bangor and the airport say emergency crews were on the scene for several hours actively working the site.

They said an Emergency Operation Center has been set up, and all flights after the crash were canceled. The FAA and the National Transportation Safety Board are investigating.

An update is expected by 8 am Monday.

The public was asked to avoid the Bangor Airport area Sunday night.

CNN reports the plane is registered to a limited liability corporation in Houston, according to federal records.

Minutes before the crash, controllers and pilots at Bangor Airport can be heard talking about low visibility and deicing.
