Yes, of course this is related to the physical properties of the emissions, but LoRa uses specific frequencies of the ISM band (868 MHz in Europe), and this discussion was about the reasons why that specific LoRa transmission worked even though there wasn't a line of sight. Airplanes could be an explanation, although your sibling comment thinks there isn't sufficient transmission power for it to be feasible.

Ah. It's most likely tropospheric ducting, I thought the top comment explained it.
