Spoilers for Masters of the Air episode 4 follow.
Last week, Masters of the Air revolved around a heart-stopping, bloody battle in the skies that split the squadron and saw some familiar faces tragically killed. Episode 4, however, takes the action from the air to the ground, reminding us that what's going on beneath the clouds can be just as dangerous as the dogfights above. It makes for a moving, mournful episode about different kinds of heroism.
