Initial data
A large black triangle was spotted in Assen:
A big black triangle, too big for a dry one, smaller than a chess piece. Flew at a constant speed. In the middle of the day. There was no discernible sound.
Original news
Grote zwarte driehoek.
ASSEN, DR — Zoals al eerder omschrijving. Grote zwarte driehoek, te groot voor een droge, kleiner als een chessna. Vloog in een constante snelheid. Met klaarlichte dag. Er was geen geluid waarneembaar.
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.
Events
Rocket launches (from space.skyrocket.de)
- Site: Vandenberg AFB, California (USA) Vehicle: Falcon-9 v1.2 (Block 5) Payload: SARah 1
