Nine killed after plane crash in Palm Beach County, Florida

Now to Florida, where nine people are dead after a private jet plunged from the sky and crashed in Palm Beach County Sunday afternoon. And investigators are now trying to determine what went wrong. The moment the Bombardier Learjet 60 crashed was captured on dash cam video. You can see it plummeting nose-first toward the ground before exploding into a massive fireball, sending thick black smoke into the air. The impact left a large crater in the road just feet from a nearby neighborhood. All nine people on board were killed. The jet was headed from Austin, Texas to the Bahamas when it crashed just before 1 p.m. Sunday. The identities of those on board have not yet been released. Air traffic control recordings reveal the pilot reported icing and moderate turbulence, then requested to climb to 37,000 feet. Moments later, the plane was in a rapid descent. We want to warn you the pilot's final distress calls are difficult to hear. 722BD, we're descending 8,000, Mayday, Mayday, we're descending 10,000 feet per minute. December 722BD, roger. Declared emergency, 722BD, we are in an over-speed condition, descending 20 to the ground, 722BD. 722BD, I'm here with you, talk to me. We are descending 22,000 feet, and we are banking. The NTSB has sent a team of investigators to Florida to determine what caused the crash. The agency is expected to hold a news conference with an update sometime today.
