"I'm really freaked out about this" - Brownsville Resident Witnesses S-shaped UFO

• When: Recently at 11:30 PM (date still being confirmed)
• Where: Brownsville
• What: Gray S-shaped solid-lit object spinning silently; Identified: Possibly an object dangling off a balcony or ledge off int he distance (misidentification or hoax)

July 28th, 2017 Update: I was fortunate enough to get a direct update from MUFON about this sighting; the San Antonio chapter investigators believe this green object could actually be something dangling off a balcony or ledge off in the near distance. Meanwhile, some on Facebook have suggested a balloon. Unfortunately, this is not the clearest-cut explanation, but it is reasonable. That said, other reports of similar  UFOs in the Texas sky have since been shared through comments online. What do you think?

Original story:
A South Texas resident witnessed a UFO shaped like a gray S and moving silently across the sky and leaving behind a misty trail. They confirmed that their friend in town also saw the UFO,  so this really rules out  a small object like a balloon. They fortunately submitted testimony to TexasUFOs:

It was traveling from east to west and moving very slow across the sky. The moon was low so it appeared to travel right over it continuing a straight path from east to the west . I've seen many documentaries and TV shows but this shape wasn't like anything I've ever heard of. It was an S shape propeller that was spinning very slow while it crept across the sky . There was absolutely no sound and no lights . I ran inside then went to my backyard and followed it until it disappeared into the distance . At that point I asked if anybody on Facebook had seen it too, A friend of mine replied that him and his mother experienced the same object . During the next 30 minutes I continue to go back outside around three times but of course there was nothing there anymore . On the fourth time is when I noticed a strange mist all across the sky exactly tracing the path of the object . I'm really freaked out about this . I'm searching for a scientific explanation and will wait for tomorrow to see if it comes out on the news or if anybody has video or pictures of this object . Did not want to call the authorities because I would sound like a lunatic. Lol.

In San Antonio, last month, a UFO case was reported to MUFON detailing a worm or S-shaped green UFO:

There have also been other sightings of S-shaped UFOs over the years, including in Belfast in 2013:
