In 1989, he formed Reaction Engines Ltd [http://www.reactionengines.co.uk] with fellow Rocket Engineers, Richard Varvill and John Scott-Scott. The enterprise is developing project [[Reaction Engines Skylon|Skylon]], and other advanced vehicles including the [[Reaction Engines A2]] hypersonic airliner concept as part of the European LAPCAT programme. The projects have involved the practical development of Hydrogen fuelled, pre-cooled air breathing rocket engines, most notably, an engine called [[SABRE]] (Synergic Air Breathing Rocket Engine) as well as the [[Reaction_Engines_Scimitar|Scimitar]] and STERN engines.
