Proxity Digital CEO Reports on Mounting the Techsphere SA-76 Airship Marketing Campaign; an Update on Cyber Scout

NEW ORLEANS--(BUSINESS WIRE)--July 22, 2004--Billy Robinson, CEO of Proxity Digital Networks, Inc. (Pink Sheets:PDNW - news) reports that Cyber Aerospace Corp., an operating subsidiary of Proxity's On Alert Systems, is initiating a new campaign to aggressively market the Techsphere SA-76 airship. Robinson noted: "Cyber was quite successful getting the attention of U.S. Government agencies to take a look at the SA-60 prototype. As previously announced, we contracted with them and launched the SA-60 fulfilling phase 1 of the contract test criteria. Now that Cyber has proven that the SA-60 can be used for national defense, we continue to pursue other Government agencies and organizations. Even though Cyber sold their SA-60, we are now mounting a new campaign to market its recently ordered SA-76 airship. The SA-76 production model utilizes both the existing and improved performance characteristics of the SA-60 prototype. We expect to have the SA-76 available in 120 days and plan on showcasing it immediately. In the meantime, we will launch the SA-76 campaign based on the success and respect we gained from the SA-60 flights." "Our Cyber Scout aircraft is in test flight mode to affirm the technology. Upon completion, we intend to accelerate the program and develop the final version which we anticipate deploying in both the civilian and military theatres," concluded Robinson.
