The grain's worthless husk that became the sky's most elegant magic trick.
means The dry, papery husk separated from grain during threshing — and by extension any worthless leftover, or the strips of metal foil aircraft scatter to confuse radar.
from From Old English 'ceaf,' the seed-coverings beaten off grain, a word shared with old Germanic kin like Dutch 'kaf.' For most of its life it simply meant agricultural rubbish — the bit you toss to the wind while keeping the wheat. The radar sense is a 20th-century military borrowing: clouds of foil that, like husks on the threshing floor, are flung out to be discarded, here decoying the enemy's instruments.
