To be declassified: UFO broke sound barrier with no sonic boom

Possibly an electronic shadow image? Or a shared hallucination? Anyway just more speculative fodder for the "Truth is Out There" folks. Actually, I really wish that the "Little Green Men and Women" or whatever extraterrestrials send a verifiable signal and/or hardware to Earth. Such might actually start an improving chapter in humanity's history, the disappointing impact to the SciFi industry notwithstanding.
