My family was outside, having to jumpstart my car, as well as my girlfriend's sister's vehicle. once we got them running, i heard my girlfriend say; "what is that?" at that time, myself, my girlfriend, a family friend, as well as our 2 adult children witnessed three reddish-orange lights in the sky. i looked for faa signal lights and saw none on any craft. they were coming from the south, heading nnw, and quite slowly...Maybe the speed of a cessna or a low-flying helicopter, at its typical service speed. they were flying in a straight line, in a loose trailing formation (one behind the other). i'm uncertain about altitude — it was already pretty dark out, or of relative distance from each other. within about a minute of observation, the third craft turned off its light. the other two followed suit about a minute after that. although it was dark, we could still see the crafts sans illumination, but i was unable to make out any definitive structural characteristics, except that they appeared to be a light grey color. they made absolutely no noise. no propulsion, whirring, anything. silent. i have been a bit of an aeronautical hobbyists since i was a kid, and having lived in the desert southwest, i am fully aware of experimental aircraft testing. this didn't feel like that. logic kind of kicks in saying "if these are top secret military craft, why would they risk flying over a heavily populated area?" they can be seen and things can go wrong. can't keep a secret if that secret crashes in downtown for everyone to see. but i digress. i can't really describe exactly what i felt...Fear? excitement? intrigue? we were so taken by what we might have been seeing, none of us thought to take pictures or video of this incident. i really wish we had. if you have any questions, please email me with the address provided. thank you.
