US Navy plane crashes into 'heavily populated' Alabama suburb, killing two

A US Navy training plane that took off from Florida has crashed in an Alabama suburb near the Gulf Coast, killing both people in the plane, authorities say.

Zach Harrell, a spokesperson for the Commander of the Naval Air Forces, said on Friday (Saturday NZT) both people in the T-6B Texan II training plane died, but they weren't immediately releasing their names.

No injuries were reported on the ground.
