I made a few changes from the original game to make it easier to dock with the plane successfully as well as disembark from it.
-I removed all control surfaces. This aircraft is now powerless to resist your advances and attempts to interconnect with it in mid-air. Practice your formation flying, docking skills, and marksmanship with less interruptions now. This also means this aircraft is non-controllable.
-The docking apparatus is now less likely to fall apart. With a light aircraft, I was able to dock with it with no damage despite over-speeding by almost 100 kph.
-The wings were tweaked and engine thrust lowered to make the aircraft maintain level flight and overall make it easy to match speeds with.

With that out of the way, here's how to play the game:

Setup:
-Download and save the aircraft under the name of your choice. I'll go with "Don McDockson"
-Select your aircraft of choice, preferably a light, supersonic capable aircraft.
-Take off and climb to a suitable altitude. 1500 meters or about 5000 feet is adequate.
-In the pause menu, select the spawn aircraft icon and select this aircraft to be spawned
-Set targeting to "Air to Air" and target the aircraft. If you cant select it you may need to spawn it in again.

Docking:
-Now just approach the aircraft. As you get closer to the aircraft (5 km or 3 mi), you'll want to gradually slow down the aircraft, especially if its heavy and fast. Also, it'll become increasingly difficult to stay aligned with the aircraft as you get closer (within 500m or 1600 ft). Use minor adjustments.
-Reverse boop time. Hopefully the magnet just booped your nose UwU. You can lower the throttle for a pretty cheap ride, or even turn it off if youre light enough. Also a nice photo opportunity, or snack opportunity if you're that guy.
Alternately if you're flying formation, well, make sure you check your throttle and alignment or you'll find yourself in a one man formation.

Disembarkation:
-You'll need a set of air-brakes for a clean disembark. Otherwise you'll need to pitch and roll in order to tear yourself from the magnet, and possibly bring the docking apparatus with you.
-Disembarking from a formation flight is pretty easy to do honestly.
