Florida plane crash: Texas family among 9 killed

The heartbreaking moments, a private jet out of Austin came crashing to the ground near Greenacres, Florida. 47 degrees Celsius. We're managing the ice, but it is moderate turbulence. The Learjet 60 was heading to the Bahamas, but that afternoon, the co-pilot could be heard telling air traffic control they were experiencing ice accumulation and turbulence. Moments later, a distress call. 722 Bravo Delta, we're descending 8,000. Mayday, mayday, we're descending 10,000 feet per minute. Communications with the plane would be lost shortly after as it came crashing down in a residential area. The identities of those on board now being revealed by the families. Austin Tech entrepreneur Adam Robinson was traveling with his wife, Helen Sharp, and their two children, four-year-old Emma and two-year-old Charlie. Alongside them was their nanny, Anita Satina, as well as the family's friends, Rachel Reed and Charmi Fair. Inside the cockpit was 20-year-old co-pilot Natalia Gidelha, with TMZ reporting the captain was 55-year-old Jeff Gregory. We do have some evidence that there was some breakup of the aircraft before impact. We're still seeking to determine that. The NTSB providing a briefing on Monday saying weather at the time of the crash will be a key factor. The weather conditions are a major focus of the investigation. What we have to determine is what the weather conditions were like at altitude. They were at about 35,000 feet. But that plane, which I've been in numerous times. At that speed, at that altitude, cannot go right into a red zone. Robert Clifford is an aviation attorney. He says the Learjet 60 wasn't capable of handling the weather conditions it went through, with flight tracking data showing it flying through a storm cell right before it crashed. I've got to assume they really didn't know what they were going into. I can't imagine any pilot deliberately flying into a red zone, but that appears to be what happened. That decision will be a part of the NTSB's investigation as they continue to comb through the crash site where the aircraft's speed left a massive crater behind. I'm lead counsel for all the families in the Boeing ET-302 case, and that plane hit the ground at 600 miles an hour. This is going faster than that, so in excess of 600 miles an hour.
