outsourcing research to unsuspecting friends

Okay guys, thoughts on the realism of someone being able to fire arrows from the back of an airborne dragon?

I'm thinking here: a dragon between 2-3x the size of a horse, gliding in very low, probably the same altitude as the target.

I think the main concerns would be draft from the wings (wings redirect air even if they're in glide position, yes? Or is that just airplane wings? what a ridiculous question, everything moving through air changes air flow) and speed.

IDK I'll probably have to do a lot of research on how wings work and airflow around them and plausible speeds for archers and things like that. Are there factors I'm not thinking of?



PS if any of you saw any of the posts that I put up earlier, oh god, please forget you ever saw those xDDD they were not meant to be public, but a few were for all of...a few seconds.
