Yes, and every airline does that. Southwest is one of the largest airlines in the world, so they will have things like that go wrong, however they don't do cartwheels killing more than half the plane, or crash short of runways killing all. I live in LA and say the BUR incident on TV. I even had a professor at UCLA whose favorite chinese restaurant was wrecked by the plane. The people still walked away, and BUR got a much needed gravel pit
