Hypotheses
Airplane / Helicopter
An aircraft heavier than air for flights in the atmosphere (and outer space (e.g. An orbital aircraft)), using the aerodynamic lift of a glider to keep itself in the air (when flying within the atmosphere) and the thrust of a power (propulsion) installation for maneuvering and compensating for the loss of total mechanical energy to drag.
A rotorcraft in which the lift and thrust required for flight are created by one or more main rotors powered by an engine or several engines. They differ in maneuverability, the ability to hover and almost vertical takeoff.
Investigation
The second object's visible condensation trail, the shape of the objects is also typical for terrestrial aircraft.
