At the San Francisco Airport

I chose to focus on "At the San Francisco Airport" written by Yvor Winters. The wording in this poem is a little strange in my eyes. It seems as if when she use Terminal, that she means it in two ways. I notice this because in the first line she says "This is the terminal, the light" but then in the first line of the last stanza she says "This is the terminal, the break." So she uses terminal in two different ways. Also, when she says "You take the way you must take." I think she says this because when you go to get on an airplane, you're doing it for a reason, you must take that way because you chose to travel, you need to get to where you're going. I also think it's interesting when she uses yard in the first stanza. She's talking about the planes in the yard rather than calling it a runway or just strictly the airport. So the use of yard in that line is interesting to me when she could've said runway or airport though yard is the correct term. I think it's ironic that she says "Beyond this point, on lines of air" because you're getting ready to fly and travel by air but also because it's called an airline so for her to use lines of air is ironic in a way.  This could also be viewed as a pun.
