Initial data
An eyewitness from Groningen writes:
The white object "flew "without sound or a"flat line".
Original news
GRONINGEN, GR — Wit object “vloog” zonder geluid of “vliegtuig streep”
Onvoldoende informatie
Op basis van de beschikbare informatie zijn er meerdere verklaringen mogelijk.
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
Externally (especially when magnified), the object resembles an airplane without a condensation trace. This corresponds to its flight path described by an eyewitness.
