Man, that is a narrow launch corridor. If the azimuth varies by just a little bit, they might be sending a few tons of red-hot metal across the length of Cuba.
Hopefully, the Range Safety folks/software are quick on the trigger. Though you wonder if a misaimed shotgun with a pellet load might cause more damage than one with a deer slug.
One thing that occurred to me, looking at this, is how little utility the Starship has…for anything related to Earth science. The available launch azimuths mean the vehicle can’t reach any orbital inclinations that’ll take it above ~35 degrees latitude unless they’re going to spend a LOT of propellant on doglegs.
I’m sure it’ll work fine for Lunar or Mars missions, though.
