It is not a matter of flight being cheap or expensive.

If you only synchronize computer "on the order of minutes" the modern
airport ceases to function as such.

During initial and terminal phases, a modern jetplane move 100m/s and
many major airports have runway use in 30 second timeslots. You do
the math.

Radar stitching requires 3msec synchronization and timestamping, throughout
the entire area being stitched, often a radius of up to 1000 km.

You have just confirmed my suspicion that you have not a wisper of
a clue about what you are pontificating about.

Never attribute to malice what can adequately be explained by incompetence.
