QT's and sump well covered?
Nope! Though I do maintain a splash guard around my QT tanks.

... at least most of the water went into my eyes and shirt ... although i feel like I need to be TTM'ed myself now just in case!
Think of it this way. The molecules of a liquid and a gas are constantly agitated and therefore are diffusing into all directions. If there is water flow in the tank, the rate of agitation is greater. This rate of diffusion per unit area depends upon the temperature and density of the substance. If the rate of diffusion from the liquid phase through the interface is greater than the rate of diffusion from the gaseous phase back through that interface then net evaporation is taking place. In our case, the air is in contact with water so the important density is that of the water vapor in the air and not the air itself.
If the system is closed the buildup of molecules in the gaseous phase would raise the rate of diffusion through the interface back into the liquid until the two rates are equal. At that point net evaporation ceases and the phases are in equilibrium.
However if the more dense gas is constantly blown away from the interface and replaced by less dense gas the evaporation will continue until the liquid is gone. Since theronts are small they are sucked up with the evaporating water and if those molecules of water are released over an aquarium, the theronts go along with. Since they are still "functional" they bring the parasite along with.
no, ick will not be transfer from one tank to another through evaporation. that does not make any sense.
I think most people thought that too up until a couple days ago. There is a new sticky at the top of the fish disease forum that provides research proving this does happen.
The more I think about it, the more I think the risk is greatest if you are using an air stone in QT. I use one when I do TT, and water is all around the outside of the tank due to the "mist" from bubbles breaking the surface. In my main QT, where I use a powerhead & HOB filter, this doesn't happen. So I assume the splashing from a HOB filter is "safer" than an air stone defusing.
And since only theronts can be transmitted via aerosol, shouldn't the risk be greatly reduced if you are already using chemical treatment to eradicate those in QT?
I have no scientific evidence to back any of this up... Just thinking out loud...

Seems like if you're doing tank transfer and empty the old tank immediately after transfer there shouldn't be any theronts should there?

Right. It is not during Tank transfer that the risk occurs, it is situating a tank that has ich next to one that does not.

Lack of ability to grasp a concept does not translate to the concept being false.
It's aerosols from breaking bubbles, splashing, etc.Since no one is running any kind of absolutely static fish holding system where evaporation would be the only factor, no need to consider evaporation. There will be some form of splashing, bubbles, etc. in any dynamic system used to hold fish

Ok, billsreef, snorvich... I've got a question for you.
We've established that the only stage of ich that can go "airborne" are free swimming theronts. Correct?
So, being theronts are what chemical treatments target, would a QT medicated with copper or CP be at risk of aerosol transmission from a DT going fallow that was infested with ich or velvet?
