A near future large city state is surrounded by a far more massive forest that is semi sentient. How do I stop them from sending up satellites, or sending up weather balloons high enough so that they can see a good portion of the planet? I also want to stop them from flying past a certain point in the forests. Essentially I want them to to have their concept of the world be limited to the fact that there is a world past the forests but they cant really see it or get to it.
I also want to preserve radio communications such that having things like blimps to act as satellites or mobile towers, is a viable strategy that is used to fill in the gaps. Things like the internet, and phones should still work. The forest in this scenario is sentient, and automatically tries to kill human that tries to enter it, so it could extend its influence into the air as well.
The planet is not Earth, and takes place in another solar system entirely. As a result the forests don't have to obey by our normal definitions of what a forest can do, in fact that large growth and sentience of forestry around the city state is partially due to alien interference, (alien as in organic, so no aliens waiting in orbit to shoot down whatever comes up).
So far I currently have a combo of artificially induced Kessler syndrome, as well as the forest being able to manipulate wind patterns and potentially the heat of the environment. However in general jets can fly fast and resist head pretty well. Blanketing the planet in solar flares constantly removes the use of electricity and communications needed in a near future setting.
Answers don't have to be in pure hard science at all, the more rational the better. Essentially I want a reason as to why humans can't peer out the forest from the air and try to fly past the forest other than just "its just magic lol, deal w/ it".
