This interesting effect is the result of the iPhone’s cheap camera:
The cheap CMOS sensor of an iPhone does not expose the whole thing at once, it scans from left to right. If you take a picture of something that moves very fast (like an airplane prop) you can get some crazy pictures out of it since each column represents a slightly different time.

Fake. Propeller is never in those positions, even though the image processor would handle the image in segments.

It is those positions. (if you take one vertical line, it is perfect) Try it yourself.

It’s not a fake, it’s an artifact of how the camera processes the image. I took some shots from my airplane the other day and get a venitian propeller.

This explains the process pretty well:

Doc is right..this effect, while interesting is highly undesirable to me..as it wrecks otherwise nice photos and videos, taking with our iPhone out the front window of the airplane.

Fake for sure. The shutter speed on the iPhone isn’t near clear enough to capture this, rolling shutter or not.

Not fake, here is a video taken just the other day…
