aerostat

For one thing, it would be severe work to draw the stranger bodily up and into the aerostat.

Then against our aerostat, and with the wind driving them clean overhead of us, come the antagonistic flying-machines.

Then the aerostat, as the great bag is called, was unrolled and spread evenly over this.

There isn't as much of that aerostat left as would make a pocket-handkerchief or a walking-stick.
