A group of planes simultaneously performs aerobatics, maintaining a given formation.

A group of planes simultaneously performs aerobatics, maintaining a given formation. What can be said about the movement of aircraft relative to each other? Why?

According to the condition of the task, all aircraft perform aerobatics synchronously, maintaining a given formation. This means that despite the movement of each aircraft separately, the distance between all aircraft remains unchanged at any time interval, that is, s = const.
Then, in accordance with Newton’s first law, we can say that the planes are stationary relative to each other.
