Underwear by Lawrence Ferlinghetti.

Still relevant.

Edit: Posting a runner-up, The Death of the Ball Turret Gunner by Randall Jarrell

From my mother’s sleep I fell into the State,

And I hunched in its belly till my wet fur froze.

Six miles from earth, loosed from its dream of life,

I woke to black flak and the nightmare fighters.

When I died they washed me out of the turret with a hose.
