• and a fluid pressurizing valve in said body and spaced from said jet propulsion discharge orifice.

A multi-unit toy missile arrangement,

• at least one unit thereof being individually self-propellable and having a respective pressurizable fluid chamber and associated fluid discharge orifice,
• at least one of said units having a body including a pressurizing enabling element as a part thereof and being other than a fluid discharge orifice, for pressurizing said one stage from an external fluid pressure source through insertion of fluid under pressure into said one unit.

The method of connecting and pressurizing two separable linearly connectible units of a jet-propelled missile arrangement, comprising

• securing said units together through a pressure-sensitive connection,
• pressurizing the rearmost of said two units while so connected, to activate said pressure-sensitive connection and without pressurizing the other said unit,
• and thereupon pressurizing the other said unit other than through said one unit.

The method of connecting and pressurizing two separable linearly connecting units of a jet-propelled missile arrangement, in which one of said units has a jet-propulsion fluid discharge orifice, comprising

• securing said units together through a pressure-sensitive connection,
• and pressurizing said one of said units through a valve spaced from said jet-propulsion fluid discharge orifice, to activate said pressure-sensitive connection.

The method of connecting and pressurizing two separable linearly connectible units of a jet-propelled missile arrangement, preparatory to launching, comprising

• securing said units together through a pressure-sensitive connection,
• pressurizing the rearmost of said two units while so connected, to activate said pressure-sensitive connection and without pressurizing the other said unit.

A self-propelled toy missile arrangement, comprising

• a plurality of separable units,
• one of said units being self-propelled and having a pressurizable fluid chamber and associated fluid discharge propulsion orifice,
• said one of said units having an individually pressurizing enabling valve therein disposed other than at its fluid discharge orifice and for pressurizing said one unit while said units are assembled.

A self-propelled jet propulsion unit comprising

• a spatially self-movable and -propelled jet propulsion body having a pressurizable propulsion-fluid storage chamber and a closable fluid jet propulsion discharge orifice connecting between said chamber and the outside atmosphere for propulsive discharge of pressurized fluid therefrom,
• and a fluid pressurizing valve in said body in fluid pressurizing connection with said pressurizable fluid chamber and spaced from said jet propulsion discharge orifice and in fluid flow communication therewith through said pressurizable fluid propulsion storage chamber,
• said self-propelled jet propulsion unit being self-propellable by force reaction to jet discharge of pressurizable fluid from said pressurizable fluid storage chamber and out through said jet propulsion discharge orifice in response to the internal fluid pressure of a quantity of pressurized fluid while in said pressurizable propulsion fluid storage chamber.

A multi-unit toy missile arrangement,

• at least one unit thereof being individually self-propellable and having a respective pressurizable fluid chamber and associated fluid propulsion discharge orifice,
• said one individually self-propellable unit having a body including a pressurizing-enabling element as a part thereof and being other than a fluid propulsion discharge orifice, for pressurizing said one unit from an external fluid pressure source through insertion of non-combustibly fluid-pressure-responsively-jet-dischargeable fluid under pressure into said one unit for subsequent non-combustibly pressure-responsive jet propulsion discharge through said fluid propulsion discharge orifice.

The method of connecting and pressurizing two separable,

• connectible units of a jet-propelled missile arrangement, in which one of said units has a jet-propulsion fluid discharge orifice, comprising securing said units together through a pressure-sensitive connection, and pressurizing said one of said units having a jet propulsion fluid discharge orifice by injection of non-combustibly-pressure-responsively dischargeable jet propulsion fluid under pressure through a valve spaced from said jet propulsion fluid discharge orifice, to activate said pressure-sensitive connection,
• said non-combustibly jet propulsion dischargeable fluid being subsequently non-combustibly dischargeable through said jet propulsion discharge orifice in response to the residual pressure within said one unit after fluid-pressure connecting-actuation of said pressure-sensitive connection as a function of the injected fluid pressure.

A self-propelled jet propulsion unit comprising

• a spatially self-movable and -propelled jet propulsion body having a pressurizable propulsion-fluid storage chamber, with a closable fluid jet propulsion orifice connecting between said chamber and the outside atmosphere for propulsive discharge or pressurized fluid therefrom,
• and a normally self-closed pressurized-fluid-containment fluid passage valve in said body at other than said fluid jet propulsion orifice for fluid passage connection between said pressurizable propulsion-fluid storage chamber and a zone exterior of said body when said normally self-closed valve is opened.
