On September 23, 1873, he debuted his new flying machine. It seated three and was powered by two thousand and eighty-four individual hummingbird hearts, which were preserved by thaumaturgical means. Rothchilde was extremely old and may himself have been preserved by thaumaturgical means. Thousands turned out to watch the maiden flight of the machine, which was heralded as a new age in manned flight. The flying machine stayed aloft for nearly eleven minutes before crashing into the Autumn River. There were no survivors, although Rothchilde's body was never found.
