The invention relates to a multipurpose aircraft, and more particularly to a hybrid dirigible. The aircraft contains a body (2) in the form of a parallelepiped, and is provided with docking means (8) comprising four rods which are connected by a frame and which can be extended from the housing (2). At least one suction element, intended for connecting to a substantially vertical surface of a building, is provided on the ends of the rods. The docking means (8) comprise grippers which are capable of engaging with the docking means (8) of another aircraft of the same design. The invention also relates to a system of aircraft, including two or more aircrafts having the above design. The proposed aircraft does not require a large space for takeoff and allows for the mass evacuation of people from tall buildings using the fastest and safest method for those being evacuated. In addition, the invention provides the possibility of adjusting the carrying capacity of a system of aircraft, in the air, in accordance with specific requirements.
