At first glance looks real, but even with my very limited knowledge about flying there's two things that reveal this as a fake.
First, and this should be obvious to anyone, where's the window? The other windows are bolted/riveted from the outside and the shape is such that if it had hinges opening inside the frame should be visible through the left window.
Second, and this knowledge has been acquired as a flight passenger, at those altitudes passenger planes fly at the speed of 1000 km/h. Anyone who's ever been in a car knows what it feels to stick a hand out at highway speed, here it would be multiplied by 10.
I'd rate this equally realistic:
