What Could Have Caused This?

I'm convinced about the cause, but still amazed I haven't taken images like this before, considering where I live. Guess I spend too much time in the swamp.

When I looked at it I perceived the point of focus was behind the plane, in the brown field just in front of the green crop row. That area looks sharpest across from left to right.

It's entirely possible that I missed focus but that alone would not account for the way this thing looks. I've shot countless OOF images and they just look OOF-blurry but not like they've been shot through bubble wrap.

That looks to me like the shimmering caused by heated air rising on a hot summer day. It's a common atmospheric phenomenon.
That would be my vote.

I'd say the heat rising off the ground.

Don't over look the exhaust from the engine.
I agree this is probably a contributing factor in the strangeness. I've done a lot of reading about this since the answers started coming in.

Heat waves, "heat" being relative. As others have mentioned, it's the difference between the ground temperature & the air temperature.
I have a ten acre hay field for my front yard & have seen these type of waves even in below freezing temps. I've even noticed it when the field is covered in snow. So, "heat waves" is kind of a misnomer, but it is easier than saying "difference between ground and air temperature waves".

Some sort of atmospheric factor showing up because of the distance between you and the plane, even though it was unexpected because it wasn't the usual summertime heat temperatures. Your camera had absolutely nothing to do with it unless they have introduced a "heatwave shimmer mode" setting recently ...

No rocket scientist here but could it be 'heat' rising off the ground between you and the subject. That's what it looks like to me! Jeff

The differences in density between those hotter rising bubbles of air and the rest of the cooler air is exactly like shooting through bubble wrap. If you take a very careful look at your shot, you might notice that as you go up from the bottom of the brown field it starts to get sharper until about the middle. At about the middle of the brown field, it starts to distort while it it seems to get sharper. At the top edge of the field, a long distance with a lot of heat bubbles in between, distortion due to temperature differentials takes over. There is no distortion due to engine exhaust. If one looks very carefully at the image of the plane, one will notice that one blade of the propeller is sticking up at the front of the plane. A 1/2000 of a second is not enough to stop a spinning propeller. The propeller was stopped at the time of the shot.
Again, this is a good example density lensing (Schlieren imaging). And this is not the only density lensing effect that can be photographed. Both the phenomenons of green flash and blue flash are caused by density lensing.

After further intense researching this could be the result of a low flying UFO giving off a magnetoacoustic wave. Whether this is a fast or slow magnetoacoustic wave is debatable, the fact that the UFO was interested in this, to them, outdated form of plant spraying certainly wasn't.

If the plane's engine was tunning, the hot exhaust could cause the difference in refractive index (so-called "heat waves") between the air behind the plane and the surroundings.
