Want the esoteric explanation for 5280 feet in a mile? From my favorite book ever, the Quadrivium [1].

5280 feet in mile = 10x11x12x13 - 9x10x11x12 feet

Radius of Earth = 11x360 miles

Radius of Moon = 3x360 miles

Radius of Earth + Radius of Moon = 1x2x3x4x5x6x7 = 7x8x9x10 miles

ALL COINCIDENCES, NOTHING TO SEE HERE, MOVE ALONG :)
