Short version: Cool dual rotor helicopter
Long version: I spotted what I thought was a regular CH47 Chinook only to find out it was anything but “regular”. This MH-47G SOA (Special Operations Aviation) version was assisting in the firefighting effort in the Napa Valley fires. The SOA regiment are know as the Nightstalkers. The MH-47G differentiates itself from the Army’s newer CH46Fs by their missionized enhancements like terrain following radar, refueling probe, advanced jamming and countermeasures suite, infrared suppressors on its engines, a cutting edge electro-optical navigation and FLIR sensor suite and most noticeably, the "Golf's" massive sponson fuel tanks which give the aircraft over double the range of its standard US Army counterpart. The MH-47G is used in heavy-lift missions such as the transportation of troops, ammunition, vehicles, equipment, fuel and supplies, as well as civil and humanitarian relief missions. The helicopter can conduct long-range missions at low level, in adverse weather conditions day and night. Which is probably why it was sent here.
One last fun fact. This thing is massive, but as big as it is, it still fits nicely in the belly of the plane my brother flies (C-17 Globemaster) without it rotors of course. #brobrag
