A system for refueling has a boom having a rigid portion and, extendible portion and a fuel nozzle at an end of the extendible portion, the fuel nozzle mates with a port on an aircraft. Control circuitry in the tanker aircraft has input elements by which an operator controls actuators moving the boom left, right and up and down, and a first imaging device proximate the end of the extendible portion of the boom, capturing images and transmitting the captured images to the control circuitry, where the images are displayed on a monitor visible to the operator. The operator controls extension and attitude of the fuel nozzle at the end of the extendible portion, according to the images displayed, mating the fuel nozzle with the refueling port, and transferring fuel from the tanker aircraft to the aircraft to be refueled.

A variety of refueling devices, systems and methods are disclosed for use in in-flight refueling. In one example one such device is towed by a tanker aircraft via a fuel hose at least during in-flight refueling, and has a boom member with a boom axis. The boom member enables fuel to be transferred from the fuel hose to a receiver aircraft along the boom axis during in-flight refueling. The device maintains a desired non-zero angular disposition between the boom axis and a forward direction at least when the refueling device is towed by the tanker aircraft in the forward direction via the fuel hose.

An entanglement device (50) has multiple elongate filaments (53) attached together to form a tassel. The entanglement device (50) is of particular use for disabling the propellers (52) of a nuisance airborne drone. When deployed, the filaments (53) spread apart over a relatively wide area before being pulled into the drone's propellers (52), wrapping around them and forcing the drone to land. Also included is a method of disabling a propeller (52) of a drone.

The present disclosure discloses a bridle for a vehicle. The bridle being connected to the vehicle and which creates a pivot point located at a location selected from: above the vehicle's center of gravity and below or at the center of lift of the vehicle, when the center of gravity is below the center of lift; below the center of gravity of the vehicle and below or at the center of lift of the vehicle, when the is located above the center of lift; and at the center of gravity of the vehicle when the center of lift is in the same approximate location of the center of gravity of the vehicle.

Various embodiments of the present disclosure provide a helicopter-mediated system and method for launching and retrieving an aircraft capable of long-distance efficient cruising flight from a small space without the use of a long runway.
