What is it that flies

and makes no sound?

On March 30, 1990, citizens of the city of Brussels spotted a large black triangular craft hovering silently over the city for several minutes. Local police officials arrived on the scene and reported observing the object as it hovered over apartment buildings. One officer reported that the object released a red glowing disk of light from its center which flew down to the ground and darted around several buildings before disappearing. The larger craft eventually departed at high speed.

The Belgian Air Force scrambled F-16s to pursue the craft once it was spotted on ground radar systems. The fighter pilots and radar operators reported that the object would dart ahead at incredible speeds every time they finally had a radar lock on it. One pilot reported the object’s speed at over 900 knots. After nine confirmed target locks the object finally vanished from their screens.
