I just attended a 7 year old girl's birthday party who was gifted a bb gun by her domestic-swilling uncle. We confirmed the temptation to shoot balloons is real. That said it seems like the other points you mentioned are working in your favor. The chances of hitting a small moving aircraft at a relatively high altitude is much lower than a 747 loaded onto a passing train. Plus I would like to imagine the temptation to shoot at something would diminish significantly as our hill billy wouldn't necessarily know it is unmanned. Not to mention anyone who has listened to a firearm safety talk is well-versed in how gravity affects projectiles. I wouldn't anticipate this being a significant problem, but it was a fun thought to entertain nonetheless.

And hey I'm just spit-balling here but isn't wind a much less of an issue at dusk, night, and dawn? Would this not be a significant factor in when you would operate? I would imagine most people shooting 747s on passing trains aren't getting out of bed to do that, after all.

In my experience around sunset and sunrise there is a period of varying wind characteristics, at least this seems to be the case in a city by water.
