👉 "Tracklessness" is a technical concept in physics and engineering that describes how objects move or behave when they are not moving. It refers to an object's inability to maintain its position relative to other objects, typically due to friction, air resistance, or other forces acting on it. In the context of aircraft, trackless aircraft would be those that have no means of propulsion or navigation, such as airplanes without engines or propellers.
