Abstract: A device for providing operating system managed group communication sessions may include a memory and at least one processor. The at least one processor may be configured to receive, by an operating system level process executing on a device and from an application process executing on a device, a request to initiate a group session between a user associated with the device and another user. The at least one processor may be further configured to identify, by the operating system level process, another device associated with the other user. The at least one processor may be further configured to initiate, by the operating system level process, the group session with the user via the other device. The at least one processor may be further configured to manage, by the operating system level process, the group session.

Abstract: An extremely quiet short take-off and landing (STOL) aircraft includes: two wings, wherein each wing comprises an engine system; a fuselage structurally connected to each wing; and a ducted fan thruster positioned on the fuselage in an orientation that is rotated relative to the typical orientation on a helicopter. An extremely quiet STOL aircraft includes: two wings, wherein each wing comprises an engine system; a fuselage structurally connected to each wing; channel shrouds surrounding at least one of the engine systems; and a ducted fan thruster positioned on the fuselage. An extremely quiet STOL aircraft includes: two wings, wherein each wing comprises an engine system, the engine system comprising two engine dual packs; a fuselage structurally connected to each wing; and a ducted fan thruster positioned on the fuselage.
