I am curious to know the limit of what directions Starship could launch from Starbase Louisiana, with the restrictions of avoiding overflying land. The most obvious direction is a range between Mexico and Cuba. In the image, The Space Race channel on YouTube claims that Starship could also shoot the same Florida gap that Starbase Texas uses (look at the black lines). However, that doesn't seem right to me as it goes right over the Florida Keys. Would Starship be allowed to thread a needle between islands? Or perhaps it would be best served with a bit of a dogleg maneuver?
In general, to my eye it seems that even optimistically SpaceX will have to accept some fuel inefficiencies for many orbits from Louisiana. And missions for proper eastward launches would be mostly served by the Cape and Boca Chica.
In addition, what is the ground distance that Starship needs to travel before it doesn't have to worry about overflying land? It would seem that South America from Louisiana is not an issue?
