chunk: Seven months after their return the Go-ahead is completed and making its maiden voyage with the president, secretary, and an aeronaut. The speed and maneuverability of the dirigible marvels a huge crowd, but are trivial compared to Robur's Albatross. Suddenly, out of the sky there appears the Albatross. It is revealed that when the Albatross exploded, enough of it was intact so that at least some of the propellers operated and slowed its descent, saving the crew. The crew used the remains of the Albatross as a raft until they were rescued by a ship. Later, Robur and the crew made it back to his secret X Island, where the original Albatross had been built. Robur has built a new Albatross and now intends to exact revenge by showing that it is superior to the Weldon Institute's Go-ahead.
