Side Enforcer was needed on an eFlight (eclipse flight) once. People from the non-eclipse viewing side tried, as expected by some of us, to get a view. They bumped into others and some issues did come up. When booking an eFlight to intercept the eclipse, make sure you have the whole row (the whole plane is best). Flight seers will try to see the eclipse - just like I would if I was stuck in one of those seats just to cover the gas costs. And yes, sometimes they do take out the seats on the eclipse viewing side.
