1. A method for deploying an airborne object utilizing a submersible transport and launch canister of the type that includes a pressure vessel in which the airborne object is stored and a cap which sealingly engages the pressure vessel, the method comprising the steps of: positioning an end portion of the pressure vessel above the surface level of a body of water;opening the cap, wherein the cap is a diver-actuated cap movable between an open position and a closed position in which the diver-actuated cap sealingly engages the end portion of the pressure vessel; andlaunching the airborne object from the pressure vessel while in the body of water. 2. A method according to claim 1 further comprising the step of transporting the airborne object while in the pressure vessel and while underwater to a designated location of deployment. 3. A method according to claim 1 wherein the submersible transport and launch canister further comprises a propellant device fluidly coupled to the pressure vessel, and wherein the step of launching comprises actuating the propellant device to launch the airborne object from the pressure vessel. 4. A method according to claim 3 wherein the propellant device comprises a pressurized gas reservoir fluidly coupled to the pressure vessel, and wherein the method further comprises the step of filling the pressurized gas reservoir prior to actuating the propellant device. 5. A method according to claim 4 wherein the step of filling comprises filling the pressurized gas reservoir with a pressurized oxygen tank while underwater. 6. A method according to claim 1 wherein the cap is biased toward an open position, wherein the submersible transport and launch canister further comprises a pull pin maintaining the cap in a closed position, and wherein the step of opening the cap comprises removing the pull pin. 7. A method according to claim 1 wherein the submersible transport and launch canister further includes a vacuum port fluidly coupled to the pressure vessel, and wherein the method further comprises the step using the vacuum port to test the sealing characteristics of the submersible transport and launch canister when the cap is in a closed position. 8. A method according to claim 1 further comprising the step of tilting the pressure vessel with respect to vertical prior to launching the airborne object. 9. A method according to claim 8 wherein the step of tilting comprises maintaining the pressure vessel at a predetermined tilt angle during launch of the airborne object, the predetermined tilt angle between approximately 250 and approximately 500 with respect to vertical. 10. A method according to claim 8 wherein the submersible transport and launch canister further includes a weighted lever arm assembly hingedly coupled to the pressure vessel and movable between a non-deployed position and a deployed position, and wherein the step of tilting the pressure vessel comprises moving the weighted lever arm assembly from the non-deployed position to the deployed position. 11. A method according to claim 10 wherein the weighted lever arm assembly is biased toward the deployed position, wherein the submersible transport and launch canister further includes a pull pin maintaining the weighted lever arm assembly in the non-deployed position, and wherein the step of moving the weighted lever arm assembly from the non-deployed position to the deployed position comprises removing the pull pin. 12. A method according to claim 1 wherein the submersible transport and launch canister further comprises a variable-density flotation device, and wherein the step of positioning comprises: increasing the buoyancy of the submersible transport and launch canister while underwater using the variable-density flotation device; andpermitting the submersible transport and launch canister to rise to the surface level of the body of water. 13. A method according to claim 12 wherein the variable-density flotation device comprises an inflatable float collar coupled to the pressure vessel, and wherein the step of increasing comprises inflating the inflatable float collar. 14. A method according to claim 13 wherein the submersible transport and launch canister further comprises a pressurized cartridge and a flow control valve fluidly coupled between the pressurized cartridge and the inflatable float collar, the flow control valve normally residing in a closed position to substantially prevent gas flow from the pressurized cartridge to the inflatable float collar, and wherein the step of inflating comprises opening the flow control valve to permit pressurized gas flow from the pressurized cartridge to the inflatable float collar. 15. A method according to claim 1 further comprising the step of installing a waterproof membrane within the pressure vessel between the airborne object and the cap. 16. A method according to claim 1 wherein the airborne object comprises an Unmanned Aerial Vehicle, and wherein the step of launching comprises launching the Unmanned Aerial vehicle from the pressure vessel while in the body of water. 17. A method according to claim 16 further comprising the step of receiving data from Unmanned Aerial Vehicle after launching the Unmanned Aerial Vehicle. 18. A method for deploying an Unmanned Aerial Vehicle from within a body of water using a submersible transport and launch canister of the type that includes a pressure vessel having an open end portion and a storage cavity in which the Unmanned Aerial Vehicle is stored, a diver-actuated cap movable between an open position and a closed position in which the diver-actuated cap sealingly engages the open end portion, and a propellant device fluidly coupled to the storage cavity, the method comprising the steps of: positioning the open end portion above the surface level of the body of water;moving the diver-actuated cap into the open position; andactuating the propellant device to launch the Unmanned Aerial Vehicle from the storage cavity and through the open end portion while in the body of water. 19. A method for preparing a submersible transport and launch canister of the type that includes a diver-actuated cap and a pressure vessel having an open end portion and a storage cavity, the diver-actuated cap movable between an open position and a closed position in which the diver-actuated cap sealingly engages the open end portion, the method comprising the steps of: inserting an Unmanned Aerial Vehicle into the storage cavity and through the open end portion; andmoving the diver-actuated cap into the closed position, andinstalling a waterproof membrane within the open end portion between the Unmanned Aerial Vehicle and the diver-actuated cap after inserting an Unmanned Aerial Vehicle into the storage cavity and through the open end portion.
