As a layman, one of the thing that fascinates me most about flying formation is not just how close the planes can get (which is fascinating, of course), but how they manage to fly exactly the same speed. Maybe I’m embarrassing myself now with stupid questions, but how accurate and how sensitive is the throttle of a plane? How precise can you set the speed, and then keep it? With the throttle, you adjust the thrust, not the airspeed, right?
