A safety device for an emergency landing of an aircraft has a runaway. A unit for retarding the speed of the aircraft is mounted in the runway and includes a plurality of rows of juxtaposed rotary bearing members, each of which is provided with a friction surface, a plurality of rotatable shafts, each of which carries each row of the rotary bearing members, and a hydraulic unit provided in each row of the rotary bearing members. A unit for braking the speed of the aircraft is fixed in the runway downstream of the retarding unit and includes a plurality of rows of juxtaposed stationary bearing members, each of which is provided with a friction surface. A unit for supporting and guiding the aircraft to move on the runway includes a base slidable on the retarding unit and the braking unit and a preventing unit for preventing the aircraft from being released from the base after the aircraft lands on the base. The safety device further includes a fire-retarding fluid provided in the runway.
