I assume they are going at slightly different speeds, but one thing got me thinking.
What if the plane the photo is taken from "falls out of the sky" (sorry, don't know the proper english terminology) ?? Remember the JAL DC-10 that fell a couple of thousand feet due to clear air turbulence (?) Wouldn't that be a potential safety risk in congested airspace? If that happens to this A/C (or both), they would sure get uncomfortably close to each other!
Any airline pilots or passengers with experience from such an event?

One time, from ORD to DFW, I was over about STL and cruising south. I was in a left window seat and was just kinda staring down. We were just above a cloud layer so there was nothing to see... or so I thought. All of a sudden a 747 tears out of the clouds headed exactly the opposite direction just to the left of our track (which is why I could see it). The separation was obviously only 1000 at that point with likely about 800 kts closure speed and it freaked me out! I didn't even have time to move... I was still sitting there, forehead pressed against the window, but my eyes were wide open just staring at the place where the plane had been moments before!
