1. A turbofan engine comprising:
- a core engine section including a compressor section feeding air to a combustor to generate high speed exhaust gases that drive a turbine section all disposed about an engine axis;
a geartrain driven by the core engine section;
a fan section driven by the geartrain about a fan axis spaced apart from the engine axis; and
an accessory gearbox driven by the geartrain and mounted apart from the core engine section and the fan section.
