I couldn't agree more. In fact, I would go as far as to say that there are known knowns. There are things we know we know. We also know there are known unknowns. That is to say we know there are some things we do not know. But there are also unknown unknowns, the ones we don't know we don't know. And you can quote me on that.
Are Jellycopter and Shy Torque in anyway related? I'm only asking because they both seem to have experienced phenomena that seems uncommon.
Has anyone else experienced anything like this?
There must be a photo out there somewhere.
Anyway, back to the matter in hand. Fog.
Radiation
Advection
Hill
Coastal
Steam
Freezing
And of course, the spooky one that I've yet to see. Shall I call it 'rotor induced fog' or does it go by another name? And is the one that lasts for hours caused by a subtle difference in rotor wash to the one that disperses almost immediately?
Can anyone else add to the list?
Serious answers only, please.
