I imagine some companies will fly banners or sky-write during the eclipse. Do all need to submit a plan and get it approved by the FAA?
Could a company actually be allowed to block the eclipse "a little" for a big festival?
EDIT: The answer here is not enough. It doesn't even talk about filing a flight plan for a specific date. So, are you saying any registered pilot (with the waiver to fly banners or to sky-write) could just wake up that morning and decide to advertise? That seems too easy and dangerous.
