This one is doing the social media rounds… again apologies for the portrait video

Nice, beware of wake turbulence though!

Probably 2000 ft rather than 1000 due to RVSM.

No, opposite direction will be 1000ft under RVSM.
Taken on smartphone. Looks A LOT closer in reality.

Agreed. People who sit up front with me are often horrified at how close it looks.

Oops, my bad. Brain fart.
It always reminds me of the importance to keep altitude with much precision. You have to get off track very far to hit another plane in IFR airspace but vertical tolerances are tight…
A while ago a BAe146 did pass us 1000ft above at FL290 and just as he was over us the plane did release for a second a kind of liquid forming a tine white flare. So besides wake turbulence more unpleasant stuff can come from above.

And also the reason why to fly in RVSM airspace you must have a working autopilot. And in practice everyone uses it.You go off altitude and can trigger an airliner RA and all of a sudden things are not looking up…

I used to fly a plane that had a little „kitchen sink“ in the galley that led to a drain outside. Maybe what you saw was sublimated coffee.
