Old Forecasts, Graded

Named forecasts traced as far back as we can read them, graded item by item as hit, costume error, miss or untestable, each with a quantity we recompute; no live predictions and no quote-hunting for its own sake.

From the Earth to the Moon: Verne’s Gun, 22,000 g or More

Verne's 12,000 yards per second over a full 900-foot run averages about 22,000 g. We grade seven of his claims: the crew a hit, the gun a costume error.
