The ferry broke down at exactly the wrong moment for everyone except Henry Ford.

On June 8, 1909, two stripped-down Ford Model Ts rolled onto a little wooden ferry at Glasgow, Mo., and crossed the Missouri River. The cars were filthy, the men inside them were running on fumes, and a Boston-built Shawmut was closing fast behind them in a cross-country race.

Then the ferry quit. The boat that’d just carried the Fords to the western bank suddenly couldn’t return for the Shawmut or the Acme, another trailing car. The official explanation was mechanical failure, but the timing looked almost theatrical. //

The Shawmut crew, stranded on the wrong side of the river, had a choice. They could lose hours searching for another crossing. Or they could aim the car toward the railroad bridge looming above the water, a half-mile of ties, gaps and terror, with no guarantee a train wouldn’t come roaring through. They chose the bridge.
