I’ve heard some weird stories about Russian airliners. Maybe in this case the pilot dragged the plane to the destination airport at low altitude and slow speed because of some malfunction or something.
I guess he could have frozen solid and become stuck to the wing somehow, and I’ve heard that people who die from submersion at extremely low temperatures can sometimes be restored to life... still, if this kid survived for two hours on the exterior of the aircraft at the typical speed and altitude of a 737 flight it’s nothing short of a miracle.
or a fairy tale.....
