A fact checking system utilizes social networking information and analyzes and determines the factual accuracy of information and/or characterizes the information by comparing the information with source information. The social networking fact checking system automatically monitors information, processes the information, fact checks the information and/or provides a status of the information, including automatically modifying a web page to include the fact check results. The fact checking system is able to be implemented utilizing a drone device.

Various embodiments of a foldable unmanned aerial vehicle having a multi-layer laminate structure and extendible arms are disclosed.

An aerial vehicle, preferably including: a rotary wing and a protection housing enclosing the rotary wing. An aerial vehicle, preferably including: a first rotary wing module including a first rotary wing and a second rotary wing module including a second rotary wing, wherein the first rotary wing module and the second rotary wing module are preferably operable between a folded configuration and an unfolded configuration. A method of aerial vehicle operation.

An aircraft has a fuselage, an engine disposed within the fuselage, a rotatable wing disposed above the fuselage and selectively rotatable about a wing rotation axis, and a plurality of interconnect driveshafts disposed within the rotatable wing, and at least one drive system component that is connected between the engine and the interconnect driveshaft is disposed along the wing rotation axis.

A yoke split into separate, individual yoke arms permit rotor blade fold about inboard yoke arm bolts in a rotor blade assembly for rotorcraft and tiltrotor aircraft. In use, the compact folded arrangement of the rotor blades reduces folded aircraft dimensions in response to ever increasing restricted storage space parameters.
