Spy Balloon Simulator
Hi I am the creator of the siteto answer everyone's questions:
1. it is supposed to be a for fun sandbox, a 'toy' if you may
2. it can in no way become a credible source for any level of military intel
3. the altitude is at 100hPa
4. I really should add a disclaimer about how this is for fun purposes only
5. adding othe levels will give me even more data chunks, but it is certainly doable
6. I want to add (programmable) steering too! will do soon
