The phenomenon is something ...

The phenomenon is something real and not visionary or fictitious. There are objects approximating the shape of a disc, some of which appear flat on bottom and domed on top. These objects are as large as man-made aircraft and have a metallic or light-reflecting surface. Further they exhibit extreme rates of climb and maneuverability with no associated sound and take action which must be considered evasive when contacted by aircraft and radar.

Quotes from the same author
