1. A gas turbine engine comprising: a fan inlet duct and a fan configured to deliver air to an exhaust nozzle, said fan inward of said fan inlet duct;a core gas turbine engine, including, in serial order extending further into the engine relative to the fan inlet, a core turbine section, a combustor and a core compressor section;a core engine inlet duct spaced from said fan inlet duct relative to a fan radial center, and for delivering air into the core compressor section; andsaid core turbine engine is centered along a first axis and said fan rotating about a second axis, and said first and second axes being non-parallel. 2. The gas turbine engine as set forth in claim 1, wherein a core engine inlet duct extends to a turning section wherein the air is turned to communicate with the core compressor section. 3. The gas turbine engine as set forth in claim 2, wherein a particle separator is positioned to allow removal of impurities from the air prior to it turning into the core compressor section. 4. The gas turbine engine as set forth in claim 1, wherein said outlet nozzle is not centered about an axis of said fan, but rather is positioned to be larger on one side of said axis of said fan. 5. The gas turbine engine as set forth in claim 1, wherein a free turbine is positioned downstream of said core engine turbine, and said free turbine receiving products of combustion from the core engine turbine, and driving said fan. 6. The gas turbine engine as set forth in claim 5, wherein said free turbine drives said fan rotor through a gear reduction. 7. An aircraft comprising: a wing, and said wing mounting an engine;the engine including a fan inlet duct and a fan configured to deliver air to an exhaust nozzle said fan inward of said fan inlet duct, a core gas turbine engine including in serial order extending further into the engine, a core turbine section, a combustor and a core compressor section, a core engine intake duct;said exhaust nozzle being vertically above a leading edge of the wing, and said core engine inlet duct being vertically below the leading edge of the wing;said core engine inlet duct for delivering air into said core compressor section; andsaid core gas turbine engine is centered along a first axis and said fan rotating about a second axis, and said first and second axes being non-parallel. 8. The aircraft as set forth in claim 7, wherein a core engine inlet duct extends to a turning section wherein the air is turned to communicate with the core compressor section. 9. The aircraft as set forth in claim 8, wherein a particle separator is positioned to allow removal of impurities from the air prior to it turning into the core compressor section. 10. The aircraft as set forth in claim 7, wherein said outlet nozzle is not centered about said second axis but rather is positioned to be larger on a vertically upper side of said second axis. 11. The aircraft as set forth in claim 7, wherein a free turbine is positioned downstream of said core engine turbine, and said free turbine receiving products of combustion from the core engine turbine, and driving said fan. 12. The aircraft as set forth in claim 11, wherein said free turbine drives said fan rotor through a gear reduction.
