Abstract: An aircraft is disclosed. The aircraft includes a first pair of wings, each wing in the first pair of wings including one or more actuating flaps configured to move to facilitate the aircraft transitioning between a forward cruise mode and a vertical hover mode, and operating in one of the forward cruise mode or the vertical hover mode. The aircraft further includes a second pair of wings, and one or more propellers coupled to the second pair of wings and oriented horizontally to provide upward lift.

Abstract: Techniques for injecting a vehicle into a high speed transportation system are described. A travel request is received from a user. The user is determined to be authorized to travel using the high speed transportation system, based on a profile associated with the user. An injection portal for the user to enter the transportation system is identified. One or more instructions for the user are provided, relating to the injection portal. A vehicle associated with the user is identified at the injection portal. Characteristics of the vehicle are sensed at the injection portal, including a center of gravity of the vehicle. The characteristics are determined to satisfy threshold values, and the vehicle is authorized for travel in the transportation system. A vehicle profile is generated. The vehicle profile is transmitted to a second controller associated with the transportation system. The vehicle is injected into the transportation system.
