An aircraft safety system comprises an aircraft body 1 with an ejectable deceleration device provided within an openable cabin 2 on top of the body. A telescopic damping mechanism 5 provided on the bottom of the body is capable of extending to a position below the aircraft wheel body to buffer an impact force. The damping mechanism may comprise at least two vertical hydraulic struts 52 connected to the aircraft body, with a deformable elastic component (53, Figure 9) connecting the struts to a friction plate 51 that contacts the ground at impact. The plate may extend along the length direction of the body. A hydraulic inclined strut (54) may be arranged obliquely between the bottom of the aircraft battle and a telescopic end of the vertical strut. The deceleration device may comprise parachutes (31, Figure 6) located on the fuselage and tail, each comprising one or more layers. A propeller located on the fuselage with a generator may be connected to a battery. Deceleration wings with an arc structure protruding toward the nose may be fixedly or rotatably connected to the aircraft body.
