In my opinion, this is a twin engined jet plane flying towards the camera. While it's impossible to discern its shape, it gets visually larger as the event progresses. Several other features of the images suggest a plane. The first feature is the obvious twin trails. These are seen quite clearly at several points in the video. Twin vapour trails often appear to spiral due to the turbulence/wake generated by the plane itself. The second feature is the physical nature of the trail. This one is essentially water vapour - there is no 'smoke'. The exhaust gases of jet engines produce water vapour and carbon dioxide in the main and no significant smoke. Rocket engines of the type used in missiles create water, CO2 and smoke, lots of smoke from the solid propellant. Only liquid hydrogen/oxygen rockets (e.g. the shuttle) create a smokeless exhaust. Of course the shuttle also has two solid rockets, which create vast amounts of smoke before they are jettisoned.
This trail is obviously water vapour as evidenced by the clear space between the plane and the start of the contrail as it cools and precipitates water droplets (steam). Rockets do not show a long clear space between the exhaust nozzle and the exhaust plume. The other feature which confims this is the banding of the contrail in areas of high and low humidity. Note how the trail seems to match the layering of the clouds. The clouds are areas of high humidity, the gaps are 'drier' and the trail disappears. These are not rocket 'stages' firing up, just condensation bands. The banding also indicates that the object remains about the same altitude as the cloud layer. If this were actually a rocket propelled missile, the altitude would be much greater in less than a minute.
The final feature is the burn length. This video is well over seven minutes long. The image suggests the event actually covered a much longer period both before and after the camera was in operation. Throughout that time, the engines are running at cruising thrust. This indicates a large fuel capacity such as is carried by typical jet liners (consider what the shuttle carries and how long it burns). The lower more distant part of the trail looks like a rocket launch due to visual foreshortening. The trail probebly extends a hundred miles away and is very dispersed. The lighting from the low sun is making this look very prominant, but it's an illusion.
Definitely an aeroplane, but spectacular to watch in these conditions.

I went back and seen what you were speaking of, but what you call the "Horizon" is nothing more than a clump of trees and brush

What ever the object was it was travelling at great speed.

I have looked at both the photo and the YouTube video several times, and I am beginning to think that this may be in fact a plane.
I took a screen shot at 0:45, and twin contrails are visible here, even though the quality of the screen shot is far from good.
Planes produce steam, missiles produce smoke. That's enough to identify this object.

"Welcome to the ATS Members Forum Chewy_Solo!!"
There are few times when a "Actual" witness comes forward for such discussions for disclosure of topics of this nature, so , "Thanks!" for that effort of first hand disclosure.
I understand when an event takes place, and the person of the event finds it unusual from accepted nature, they run and get the video-camera, camera, etc. which takes time. Now, as the witness,
"How long did you witness the event?"
"Did you see as it was happening from the time it broke the surface of the water, or did you capture the time you sighted this event immediately after you seen it?"
"You said you had heard "NO" sound what so ever in your earlier post, Have you ever seen anything like this before in this region of the Keys?"
"Was it travelling away from you, or, as you had said on the video, heading towards the SW from where you were?"
"After it was airborne, did it make "Any" noise at all, Rumbling like thunder or the like, and how far off would you say that the point of ascension had taken place?"
I am glad you came forward, and "Kudos" to easynow for the extra added efforts of actually being able to contact the videographer of this event, it takes some real inquisitive minds to produce actual members for their input of such events.
"Starred and Flagged for easynow!!!"
