HCNN - 4 People Killed in Plane Crash Following Sonic Boom

The Air Defense Command scrambled fighter jets to intercept a private plane that was flying over Washington, D.C. When those jets took off, they created a sonic boom that was heard in the area. After the fighter jet pilots intercepted the plane, they saw the pilot slumped over. That plane later crashed in Virginia, killing four people including wealthy realtor Adina Azarian. The Pentagon says the plane was not shot down and it likely crashed when it ran out of fuel.
