Ukrainian Vladimir Tatarenko has developed a system that would save passengers on a plane in case of crash. If a problem occurs during takeoff, landing, or even in flight, the cabin containing passengers separates from the aircraft fuselage. This capsule is then dropped, this fitted capsule parachutes to retros and a buoy system, could help to land or to alight on water smoothly. Passengers will be located safely. To compensate for the weight of all these devices, lightweight materials would be used for aircraft construction. The research Tatarenko VN had also proposed a similar concept to it.
