Tragic Virginia Private Jet Crash Claims Lives of Accomplished Pilot and Single Mom

Four victims, including a luxury real estate broker, her 2-year-old daughter, her nanny, and a "top shelf" pilot, died in a private plane crash in Virginia. The cause of the crash is under investigation, but experts theorize that the plane could have lost pressurization in the cabin, causing those inside to pass out. The pilot, Jeff Hefner, had decades of experience and was survived by his wife and three children.
