Four decisions, one date: what May 31 teaches about cost, risk, and the names that outlive the buildings

Four May 31 decisions across 124 years — Madison Square Garden's 1879 opening (brand equity as permission structure), the Titanic's 1911 launch (tail risk suppressed for product narrative), the Trans-Alaska Pipeline's 1977 completion ($863M estimate → $8B actual), and Air France's 2003 Concorde retirement (sunk-cost fallacy institutionalized in supersonic flight).

May 30 — the proving ground, the long runway, the fixed-price bet, and the business records

Four May 30 decisions across 113 years — Carl Fisher builds a racetrack as a research lab that produces the rear-view mirror; Airbus enters commercial service with 6 orders and nearly collapses during an 18-month order drought until a free trial wins the first U.S. buyer; SpaceX ends America’s 9-year dependency on Russia with a $3.1B fixed-price contract that outperforms Boeing’s $4.2B Starliner by 16 missions to zero; and a Manhattan jury convicts a former president on 34 counts for coding a hush-money payment as legal expenses.

May 29: a 5-cent soda that outlasted its formula, a watch company that won Everest without reaching the summit, the vote that built Russia's oligarchs, and a president re-elected four days before resigning

Four May 29 decisions across 129 years — Pemberton's $73.96 first Coca-Cola ad (1886) launches what becomes a $275B brand built by Asa Candler's marketing instincts, not Pemberton's formula; Rolex (1953) publishes its Everest ad three days before Smiths — whose watch Hillary actually wore — and wins a 70-year brand association from John Hunt's honest durability endorsement; Yeltsin's 535–467 parliamentary election (1990) triggers shock therapy and the loans-for-shares auctions that hand Norilsk Nickel ($170M), Yukos ($310M), and Sibneft ($100M) to connected bankers, creating the oligarch class; Blatter wins re-election 133–73 at FIFA (May 29, 2015) and resigns four days later after Coca-Cola, McDonald's, Visa, and Budweiser coordinate a single-day public demand.
