probably the same amateur radio people can connect to people halfway across the globe; bouncing off an atmospheric layer.

That doesn't work well on 433MHz oder 868MHz. Ionosphere reflection stuff usually happens <30MHz.
On VHF/UHF it's usually atmospheric ducting where radio signals are getting reflected between two layers of air.
