Swinging away above the clouds that are nestled in a gigantic mountain range far below is totally unexpected, and we immediately register it in the impossible range of things. We appreciate the unlikeliness of it and try to figure out how it could be possible, but we can never fully reconcile it emotionally in spite of believing your explanation. So it remains in the realm of nebulous possibilities, a scary but fun photo that we will never emulate. Brilliant framing and timing.
I would not be able to resist compositing it with a photo shot out the window of a commercial jet, one of those that shows the wing.
