A military jet hits a bird in the skies over Florida, but when the remains are analyzed, the results are astonishing: The DNA is not from a bird -- it's from a deer! The pilot confirms that no deer was hit on the runway, and that it was definitely a strike at altitude. The team asks, can reindeer really fly? And on the Great Barrier Reef, hundreds of marine turtles are washing up dead and emaciated. A crisis team is sent to look for answers: Why are these ancient animals going hungry?
