I hadn't thought about the audio-angle of the recording. I'm not saying the guy should have been locked up or anything. But, I didn't think about recording of voices around the window mounted rig. And, I guess I could see the crew going either way on whether it's "allowed" ... whether takeoff/landing, could damage the plane, complaint of a nearby pax, etc. 17 hours in a metal tube causes all sorts of reactions and behaviours by people.
I mean I get it. Lots of reasons or for no reason at all. Maybe a certain cloud formation. On a train with varied scenery going by for hours, nifty. That's why I kept coming back to this one before eventually posting it. More power to the flyer for doing it and posting it.
