A method for launching an object from a flying apparatus according to which method: a. to a container , belonging to the flying apparatus, wherein the container comprises at least a bottom and a casing , a spring is placed against said bottom, which spring is a compression spring and has been loaded or is loaded into a tension state so that its propulsive force (F) is directed to the direction of the object , b. said tension state of the spring is locked or has earlier been locked by a fixing device so that a tensile load caused by the propulsive force (F) is directed to the fixing device, c. the object to be launched is placed into the container as an extension of the spring, d. the fixing device is a cord, a wire, a bar, a strip, a string, a line or some combination of them and its tensile strength (T) is greater than a tensile load caused by the propulsive force (F) of the spring to said fixing device, e. the tensile strength (T) of the fixing device is reduced to be less than said tensile load by heating, burning or melting said fixing device using electric energy, f. the fixing device breaks, the spring expands into the direction of the object and the propulsive force (F) of the spring pushes the object out of the container and detached from the flying apparatus, wherein an electric current is conducted through a part of the fixing device to be broken that is of electricity conducting material, whereupon electric energy converts into heat energy in the fixing device and the temperature of the part of said fixing device to be broken raises in an amount that its tensile strength (T) decreases below the tensile load caused by the propulsive force (F) of the spring to said part; or in that leads are installed in connection to the fixing device and electricity is conducted via the leads, whereupon an electric arc is formed between the leads, heat energy of the electric arc heats, burns, or melts the part to be broken of the fixing device in an amount that its tensile strength (T) decreases below the tensile load caused by the propulsive force (F) of the spring to said part. a. to a container , belonging to the flying apparatus, wherein the container comprises at least a bottom and a casing , a spring is placed against said bottom, which spring is a compression spring and has been loaded or is loaded into a tension state so that its propulsive force (F) is directed to the direction of the object , b. said tension state of the spring is locked or has earlier been locked by a fixing device so that a tensile load caused by the propulsive force (F) is directed to the fixing device, c. the object to be launched is placed into the container as an extension of the spring, d. the fixing device is a cord, a wire, a bar, a strip, a string, a line or some combination of them and its tensile strength (T) is greater than a tensile load caused by the propulsive force (F) of the spring to said fixing device, e. the tensile strength (T) of the fixing device is reduced to be less than said tensile load by heating, burning or melting said fixing device using electric energy, f. the fixing device breaks, the spring expands into the direction of the object and the propulsive force (F) of the spring pushes the object out of the container and detached from the flying apparatus, <EOS>
