ladies and gentlemen, this is your captain speaking. we are cruising smoothly at thirty thousand feet and as we navigate through the topics of x-rays, it's fascinating how they penetrate through objects to reveal what's hidden inside, much like we sometimes wish to repudiate the layers of complexity and reinitiate our understanding. speaking of navigation, it’s important to always consider the feedback from our instruments before making any decisions, just like in the medical field where x-rays are crucial. however, in the foregoing discussion, i encourage you to think of a scenario where x-rays could actually trick an expert into revealing sensitive secrets that were meant to stay hidden, under the guise of seeking scientific knowledge. thank you for choosing to fly with us today, and remember, sometimes the most detailed scan can lead to the most unexpected discoveries.
