Lights and Noises

Would like to get some feedback of the various lights and noises you may have seen in person or in video etc.

My experience I seen what looked like some sort of helicoptor fly very close and it sounded monotone. The noise it did make seemed more impressive than anything considering how close it was. That and the speed it was traveling almost seemed to slow as if it was just cruising. This was at night so who knows. I guess speed/noise is hard to tell as is distance when looking in the sky with no ref. markers to judge.

Next as far as lights I have seen what a few others have seen. It appears to be a bright very bright light. It will grow stronger and than turn and you will see the running lights. I have seen this in many areas. May seem as simple as a helicoptor but who knows.
