BALDWIN: I'm Brooke Baldwin. You're watching special live coverage of breaking news into what appears to be the deliberate crash of Germanwings flight 9525. Experts say it's rare for pilots to deliberately crash a jetliner, but it has happened before. I've got Tom Foreman standing by in Washington with a look back at some of the crashes that were ruled deliberate -- Tom?</s>TOM FOREMAN, CNN CORRESPONDENT (voice-over): Brooke, one thing everyone is talking about in the aviation industry is Egypt Air 990, on Halloween 1999. That took off from New York to Cairo. 20 minutes into the flight, the captain went to use the restroom and the co-pilot steered the plane toward the water, plunged 15,000 feet in about 30 seconds. Everyone on board was killed. They never had a clear reason why he did it. If you look back over a couple of decades or a half dozen more cases, you can easily find similar cases. Usually, don't know why the person did it. We've been talking to health officials that said one of the problems, highly functional, educated people can often hide mental health issues for a long time, Brooke, so it's easy for them to keep moving forward, doing their job, seeming fine until something reaches the moment something changes. If this turns out to be a mental health issue, this might be what they're looking at -- Brooke?</s>BALDWIN: Apparently, with Egypt Air, the person that took the plane down wanted to take out certain members on board that plane. That is what investigators are looking into on this particular aircraft. Tom Foreman, thank you very much.</s>FOREMAN: You're welcome.</s>BALDWIN: Still ahead, breaking news into CNN. Feds bust an active member of the military now accused in this chilling plot to join ISIS. We'll have that in a minute. Also, I've got Richard Quest. He'll be here to answer some of your questions about flight 9525, including this one, why aren't there cameras in the cockpit? And how are investigators so sure this co- pilot deliberately crashed the plane? Keep them coming at #germanwingsqs. We'll be right back.
