On one of the TV shows about UFOs one guy made an interesting discovery.

He showed a fuzzy photo of a UFO taken with a camcorder or
everyday still camera. Then he showed a picture of a
similarly shaped UFO that also was fuzzy. The difference was
that that shot was taken by a high-priced government
telescope used to track missile launches.

The conclusion I came to was that whoever was flying these
things had a propulsion device that ionized the air around
the vehicle.

Pushing the envelope, could that be why they can apparently
zip around frictionless with no sonic boom?

Many others have made your excellent observation.

And some supposedly in the know report that such is true.
