Hyperion C. Blackadder

Hyperion C. Blackadder was an Irish missile research engineer and an important figure in the history of intergalactic travel. While working on Saturn's moon Tethys, Blackadder stumbled across the principle of hyperspace drive, and found himself in the Jupiter's moon Io, before even realising what had happened. He spent the following four years trying to return to Tethys. Blackadder's discovery revolutionised human intergalactic travel. Because of this, one could travel from Odin-3 to Xeros-9 in under a week. (PROSE: Doctor Who and the Leisure Hive)
