Ballistic means it follows a ballistic trajectory, as in it is governed by gravity and inertia. Flight is typically governed by aerodynamic forces and ballistic trajectories are normally considered undesirable by pilots and passengers alike.

"Ballistic just means that there is no active propulsion."

"Ballistic means it follows a ballistic trajectory, as in it is governed by gravity and inertia."

If we're being pedantic about explicitly not-the-point of my post, drag is an aerodynamic force and included in ballistic calculations. And gliders are not ballistic and are not under active propulsion.

Cool.

Now that we've cleared up that we can both understand definitions, try doing "There's nothing ballistic about laminar flow."
