In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium.
In both pictures here, you can see how the change in medium has redirected the light waves.
This I understand. However these images show a change in medium that cause the refraction. There was no change in medium in my video.

I was in the military. If you can see it, we can hit it.
OP
From what I understand to be true, the military can hit far beyond what we can see.

What if the medium was the air in the distance between yourself and the object?In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium.

Good question! Notice in the example you posted it shows the actual boat at the bottom. Above that shows the inverted mirage. The other illusions show the boat standing above the water appearing as though it is floating in the air. If you look at my video, none of these illusions are present. You can clearly see the boat right-side up and in the water.

They can - also my understanding, that I'll take the brave leap out and say is in fact factual. This would be in itself exclusive to the hitting of what can be seen, it seems. I'd say also that they could easily do both.
Have worked in this industry, but can’t say much about it. The best testimonial was from a Iraq war veteran I hired. He told me they were so confident in the accuracy of the rounds that they would call in fire support to hit an enemy position across the street from them if they were pinned down. This is with a round that would fly 25 miles to get there.
The Bismarck struck the battleship HMS Hood...which was only 104 feet wide...from 15 miles away...80 years ago.

Okay, so then that boat must not be as far out as originally thought then, right?
That monstrous oil rig on the other hand...

Wow. I mean, I could see if it was maybe 208 feet. 104 seems quite risky.
OP
I know for a fact that the oil rig and Catalina island are at least 25 miles from my friends back yard where I took the video.
Santa Catalina Island to Sunset Beach
Here is the Google map showing Catalina island, however the oil rig is not shown on this map. The oil rig is indeed farther out from Sunset Beach than Catalina. Using Google Earth, the actual distance from my friends house to Catalina island is 27.8 miles. The oil rig is farther out to the south west. I'm trying to get the exact location of the oil rig, but it does not show up on Google.
Aaahhh….but there is a change in medium(or thickness there of) the atmosphere, from your perspective, is thickest(distance to stratosphere) at the horizon.In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium.

But, what about the boat? From the greater visual clarity of the boat as compared to the oil rig, it seems like the boat is significantly closer than the rig or the island.
Exactly. The change in medium does not have to be a change in substance, as in going from gas to liquid.
It can occur when going between different densities of the same substance, such as air masses of differing densities.
OP
I will be going to the beach again, with camera on a clear day and know the exact location and distance of what I'm videoing. This has my curiosity up.
How will you be able to pin-point where the boat was?
OP
I can't pinpoint where the boat was. I can take a new video over a distance than can be measured. I was not planning on taking videos of boats that day, however this does have my curiosity up. I can pinpoint the distance from my friends home on the beach and perhaps take a video of Catalina island with a known actual distance. Now I just need to have a clear day in L.A. These are few and far in between.

Boat is much closer than the rig. Rig is also very tall. Add refraction in.
Voila.
Even not accounting for curvature, the 3000mm lens cannot resolve a boat at 25 miles.
