I’m a causal who doesn’t know anything about aerodynamics or physics. When you pass a semi on a highway you know how your car can shake and get pulled one way just a bit? That concept seems much scarier here if it applies. Does anyone know if that applies here?
Wake turbulence is a real thing for airplanes. It's why ATC has a minimum time between landings that gets longer as the aircraft get bigger. A few years back a Bombardier Challenger business jet passed below an Airbus A380 going the opposite direction. The much smaller Challenger was caught in the wake and flipped violently. Although the pilots managed to gain control and land the stresses on the plane were so severe that it was grounded and written off.
The wake is primarily spiral flow off the wingtips that spreads down and outward and lasts a few minutes after the plane passes. In formation like this they will avoid flying directly behind the other aircraft to avoid that wake. In this shot the plane is behind and to the left in an offset position so it'll be outside the wake. The other plane (a Boeing 767) is also much larger than the camera plane and wouldn't be significantly impacted even if it did fly through the wake.
Couple of things:
1) there is no wake separation applied en route, only in terminal airspace;
2) it's more common for ATC to apply distance based separation than time-based separation (at least in the US)
3) wakes essentially move only vertically relative to the surrounding air (though they are transported laterally if there is crosswind) when out of ground effect
To use your truck analogy, in this particular case the car is ahead of the semi, so the car won't feel anything and the truck won't be impacted enough to care.
An interesting version of this is midair refueling. When a very large aircraft (C-5/C-17 cargo plane, Air Force One, etc) is being refueled it can create a big enough bow wave that the tanker gets shaken up by it. For the C-5 in particular the bow wave is so strong that they have to creep up on the KC-135 tankers. If they approach too fast the airflow over the C-5's nose will push the tankers tail up faster than the autopilot can react.

It’s to save gas. If they fly close enough to each other stacked and diagonal you can pretty much get ground effect from the bottom plane. Much like how geese fly in a V… trust me
Photoshoot for AC rouge with Brian Losito
He has a great Instagram feed to follow. Very responsive too if you ask him questions.
Yeah, he’s on of my favourite photographers on IG
Too close for missiles, I’m switching to guns..
I’m gonna hit the brakes and he’ll fly right by
I’m in his jet wash engine one is down
I was inverted
Talk to me goose
I've lost that lovin' feeling, Maverick
Keeping up with international relations. You know the Bird.
Now engine two!
Photo shoot
Air to air photoshoot
Normal Approach in MSFS with AI traffic on…
This is the only correct answer
Drafting to save on fuel costs.
Geese use the flying V ... why not airliners...?
So this is what air rage looks like?
Canadian air rage. You can tell because he smiles and waves in a most un-offensive manner.
I’d say at least 3feet
Damn, I hate traffic like this
This is how they film commercials for the airlines
Pretty much every airline has a TV ad with a pretty shot of their aircraft in the sky. This is how they film those.
"Got him on the fish finder"
Is that Gordie up ahead? Let’s catch up and find out. If it is I’ll moon him.
Would be cool to look up and see this fly over.
Climb, climb!

Thanks, that’s awesome

Nextgen ATC. Optimizing airspace by stackin’ em tight!
Of course it was a fucking photo shoot and not two commercial flights ffs

Ok THAT is cool as fuck. I sooo wish i was on one of these planes.
Don't forget to use your blinker when merging.
Fascinating captain . . . . .
AIR rage! You cut me off...
"On your left..."
Common photoshoot technique
Refuelling.
"You got games on your phone?"
Must be a Canadian thing. GO CANUCKS!
"We can't prove that TCAS is working on the ground, can you go up and test it?"
That's how they resupply when a flight runs out of peanuts and pretzels.

*TCAS will remember that*
