The envelope bore the brunt of it. Suddenly the whole ship vibrated and visibility whited out; the gondola rocked and bounced. Somewhere, over the rumble of the fall, a brief scream faded. Sunset and Cook lost their footing. Cook fell heavily to the deck.

Her safety line tautened, arresting her tumble, then gravity promptly took over. She fell right past the edge of the remaining platform to swing in open air.
