From the CNN link above:
CNN aviation analyst Peter Goelz said a type of engine that is usually "extraordinarily reliable" likely came apart on the Southwest flight, causing today's emergency landing.
"I have been on scene on these kinds of disasters — they're very rare, the turbofan engine is extraordinarily reliable," he said. "But in this case it looks like it came apart midair."
My bold. Is this the best CNN can do in terms of an “aviation analyst”?
