it is not just a camera optical illusion, it appears the same to the eye too, and indeed the way it appears depends on the rpm. I haven't seen them on real airplanes, yet I have seen them on plenty of real helicopters. the same effect actually can be seen on any rotating blades (propellers, car wheels protection plastics, old trains spiked wheels, etc).
where are real pilots flying single engine aircrafts (and not flying them just once), to answer this?
ps: and I'm not angry at all, just letting you know.
