Granite House

The colonists build their principal dwelling into the eastern cliff.

A natural cavern ninety feet above the sea becomes a secure suite of rooms, stores and workshops. Its windows overlook the mouth of the Mercy and the small offshore islet.

Verne says

Could a balloon fly this far in 1865?

>6,000 miVerne’s stated distance
4 daysTime aloft
>63 mphMinimum average speed

Maintaining that average for ninety-six hours would carry the balloon across a continent and most of the Pacific while it continuously lost lifting gas and ballast.

Fact-check

Four days in a hurricane exceeded every record

≈380 mi1836 distance record
18 hoursRecord flight duration
NoDirectional control

A free gas balloon moved with the wind and could only change altitude. Verne’s craft survives hurricane turbulence, rain loading, and gas loss for more than five times the record duration, carrying five people and a dog until it encounters land.
