A heavy lift airborne transport device is disclosed, which is capable of transporting people and goods from one location to another. The device includes a circular shaped body. A uniquely designed propeller is mounted on the top of the body. The propeller blades produce a low pressure region above the device. The difference between the air pressure on the bottom and the top of the device's body provides the uplift force for holding the device in the air. The device is capable of vertical takeoff and landing. A horizontally mounted propeller located at the back region of the device's body slightly lifts up the backside of the body, facilitating the forward movement for the device. A land and sea landing version of the device is disclosed as well.

A vertical take-off and landing (VTOL) aircraft provides transportation to users of a network system. The network system may include multiple aircraft or other types of vehicles to provide multi-model transportation. An aircraft may include a fuselage, a truss coupled to the fuselage, and multiple distributed electric propellers coupled to the truss. The distributed electric propellers may be positioned on at least two different planes. The fuselage may include a cabin having one or more seats for the passengers arranged in a configuration that has a compact footprint, provides legroom, provides visibility to surroundings of the aircraft, or facilitates convenient ingress or egress of passengers. The aircraft may open a port cabin door and starboard cabin door for simultaneous ingress or egress of passengers.

A stairway for aircraft is disclosed which includes first and second stair halves, one which nests in the other. The first half is hinged to the doorway and the second half is hinged to the first half. A mechanical resistance system uses different devices to allow for the airstair to be damped when switching between modes. A retracting arrangement is also disclosed.

An aircraft stair system is provided with flexible bumpers configured to prevent abrupt impact of the first structure against the second. Each of the bumpers has a flexible body, a base portion, and a lever arm extending out over the base to create a gap and an open mouth.

A vehicle (600, 700) is disclosed. The vehicle (600, 700) includes a body forming a door opening. The vehicle (600, 700) also includes a first hinge (607, 707) coupled to the body. The vehicle (600, 700) further includes a door (608, 708) coupled to the body at the door opening and movable between an open position and a closed position. The door (608, 708) includes a first door portion (608A, 708A) including a first end and a second end opposite the first end. The first end is coupled to the first hinge (607, 707) and configured to rotate in a first direction in the open position and the second end is coupled to a second hinge (609, 709). The door (608, 708) also includes a second door portion (608B, 708B) coupled to the second hinge (609, 709) and configured to rotate at an angle to the first door portion (608A, 708A) in the open position and form a single surface with the first door portion (608A, 708A) in the closed position.
