In this Deep Dive episode, our hosts discuss the 1947 Spruce Goose flight, Daniel Boone’s role in early American transportation corridors, and the Eiffel Tower’s planned dismantling after 20 years that never happened.

• 📜 The Spruce Goose: Howard Hughes's massive wooden flying boat made one brief flight in 1947 — a moment that combined ambitious engineering, material constraints, and the need for unique infrastructure (docks, runways, facilities) while crystallizing Hughes’s mythic showmanship.
• 🎂 Birthday spotlight — Daniel Boone (1734): Boone’s trailblazing and repeated routes functioned as proto-infrastructure, creating waypoints and corridors that lowered travel friction, guided migration and trade, and eventually hardened into formal roads and settlement patterns.
• 💡 Fact of the day — Eiffel Tower: Originally slated to be dismantled after 20 years, the tower’s continued utility (communications, tourism, symbolic value) shows how “temporary” structures can become permanent features of a cityscape.
