A counterexample to the majority view in this thread: The idea is cool, but I could never take a flight in a windowless plane. While I am generally only mildly claustrophobic, "artificial windows" have always induced an uncanny valley-esque increase in discomfort due to the lack of parallax; the reminder of what's outside while still being evidently not a direct view might well be worse for me than no window at all. Though I'll usually spend flights reading or on my laptop/phone, the presence of the window in my peripheral vision is essential for my comfort even on a shorter flight, and the concept of being trapped in a box with no direct view of the outside (and no guaranteed knowledge of if something goes wrong) for 10-12 hours is the stuff of nightmares. The fact that digital windows can fail or display false information only makes it more horrifying. Several commentors have made the comparison of either nighttime flights or a train in a tunnel. Nights are never pitch-black, and between moon/starlight and the plane's own running lights, even if you encounter high-altitude clouds there is always some visible outside environment. The same goes for train tunnels, with the replacement of tunnel lights instead of moonlight, and significantly more tactile feedback on the tracks compared to an airplane.
