I feel like it's always a highlight to the guests I've seen on the tour -- the entire tram goes quiet and everyone takes out their phones, plus they show the clip featuring one of the most famous actors of all time shot by arguably the biggest movie director ever -- I hardly think "no one" knows what it is from.
With that said, the set has become a former shell of what it once was. They've cleaned up a lot of the debris, and the pathway from the Terror Tram gets wider every year to the point that there's not much of a crash site left other than the plane. I think the set has done its time if they're going to just keep diminishing what it is and I'd prefer they add something else. I loved it when it first premiered, but it's no longer as visceral because it doesn't feel as real, due to what I am assuming is safety guidelines for guests to walk through it. Lord knows we don't need another Purge or zombies section on the Terror Tram since it's the only thing that fits that aesthetic. I hope whatever comes next can fulfill 2 needs -- something with wow factor and can also work in tandem with the Psycho sets for the Terror Tram.
