Understanding all kinds of English accents can improve empathy and learning—and even be a matter of life and death

In a 2019 sketch from the US late-night comedy show Saturday Night Live (SNL), the actor James McAvoy plays a Scottish air traffic controller attempting to help a US brand integration manager (Mikey Day) land a plane in distress, because the pilot has been knocked unconscious. The fact that Day's character is not a pilot only partly explains why the mayday call is not a success. McAvoy lays on thick Glaswegian, in both accent and vocab, and none of the Americans on board understand a word he says.
