Geoengineering Test Quietly Launches Salt Crystals into Atmosphere

[ArMaP]

Well then, if it’s supposed to be over the ocean and not the land, how high before the jet stream takes it where it will?

I don't know how they are going to do it, so I cannot answer that.

I have very little faith in them being able to control/contain anything.

I don't think they can "control" it, but knowing (more or less) how things work it's not that difficult to know where to do the spraying for it to finally fall over the ocean.

But, even if it falls over land, I suppose it depends on how much salt they use on their spray, as the idea appears (to me) to be using it on already existing clouds to make them more reflective, so I don't think the salt will be in a concentration high enough to do any damage.
