The old Tornado jet engines can run, basically, everything. For a while that is, the need serious overhaul after running on Diesel for example after low singel diggit flight hours. The reasoning back the, at the hight of the cold war, was to be able to move the squadrons quickly to dort strips an roads and out of harms way, and back to an airfield, in case nuclear strikes and stuff. For that purpose using Diesel is helpful I guess. It was never done, exept for trials as far as I know.
