"This paper describes the technical characteristics, lifecycle emissions and economic competiveness of a hypothetical liquid natural gas (LNG) powered turboprop when introduced into a market place...[LNG] is attractive from both an economic standpoint and a lifecycle emissions standpoint but has technical difference that require an all new fuselage and thus new aircraft design."
