Waiting for nightfall ...
All of a sudden ...
UFO !!!

I distinctly saw at least one, and possibly 2 blinking strobes "on" the object. The one definite strobe was exactly where the tail strobe on a commercial jet would be, and given that that portion of the video was shot during civil twilight, it's entirely possible that an airplane would be at a high enough altitude to still be bathed in sunlight.These two things lead me to believe that your unidentified object was, in fact, an airplane. I could go on with other bits of evidence, but I think that what I've already put forth is enough.

Searching for the planet Jupiter, and the star Regulus from the constellation Leo. This evening, there was this eerie sound. So I just quickly captured it on my cell phone video.  A bit suspicious, my internet blacking out as I uploaded the video, but it made it to YouTube.

I'm sure I can hear a jet engine sound on the video.

My feeling is the same as Daves, it's an airplane, shame that.

I thought it was the moon, then found the UFO came later. Yep I can hear the aircraft too.

Made it through the night.  No alien abduction, or men in black showed up. Shame that, the planet Jupiter, and the star Regulus, with the moon in between, and all a two megapixel cell phone captured was an unidentified flying... Airplane!

Oh, and may I point out friends... The YouTube account that was uploaded to was iSyFy...  So, in all honesty, there was always a Sci-Fi theme to this thread from the very beginning.  I didn't emphasize that before, so as to not spoil any fun.

Seriously though...  I saw the planet Jupiter, with the naked eye, which was easy to locate with the position of the moon. Unfortunately, it did not show up on any of my cell phone footage.
