Proxity Digital Subsidiary Cyber Aerospace Presents Spherical Airship to Military and Governmental Representatives

NEW ORLEANS & ATLANTA, April 1, 2004 (PRIMEZONE) -- Cyber Aerospace Corp., the operating subsidiary of On Alert Systems, Inc., a Proxity Digital Networks, Inc. subsidiary (Pink Sheets:PDNW), announces they successfully presented the AeroSphere SA-60 airship and its technology to the military, government representatives, federal contractors and media. The event took place on Monday at a location on 10th Armored Division Road outside Ft. Benning, GA. Cyber Aerospace expects to provide airships to Ft. Benning's Soldier Battle Lab for testing and use by the military.

The AeroSphere SA-60 employs a spherical design and currently holds the world altitude record.

Billy Robinson, CEO Proxity Digital Networks Inc. notes, "We are marketing the airship primarily to the U.S. military and our foreign allies for use in battlefield surveillance. Various models can monitor war zones and combat areas with multiple systems platforms from all altitudes up to 70,000 feet. Border patrols can also use them to keep us secure from drug traffickers and illegal aliens. Priced in the $5 million range, the AeroSphere SA-60 low-altitude airship is designed to hover at 15,000 feet for 48-72 hours with a full payload of cameras and sensing devices. They can also be used by telecoms to complete wireless dead zones."

Cyber Aerospace Corp. purchased the AeroSphere SA-60 airship from Techsphere Systems International, LLC., a manufacturer of low-, mid- and high-altitude airships. Cyber also holds the exclusive global government marketing rights to the existing and advanced airship designs being developed for Techsphere by 21st Century Airships, Inc., a research and development company of lighter-than-air crafts. Techsphere has contracted with the Georgia Tech Research Institute to provide engineering for the integration of components for the automation of the airships. The Georgia Tech Research Institute and Techsphere will design and implement special airship applications for Cyber Aerospace clients for use in civilian, military or homeland intel missions.
