Is NOx an issue if it's far away from humans?

  probably not, but the plane still has to takeoff and land sometimes. tbh, I'm not sure exactly how hydrogen combustion compares to hydrocarbon combustion in terms of environmental harm. I suspect it's still a lot cleaner overall. a lot of people think hydrogen combustion is totally clean and just creates water as exhaust, so I like to point this out.
