This information is being provided as it could prompt inquiries from your readership or listeners in the vicinity of Plum Brook Station. The aerostat will provide a safe and cost effective proving station for observation and communication technologies before testing at high altitude on expensive stratospheric vehicles. The U.S. Army Space and Missile Defense Command's Battle Lab out of Colorado Springs, Colo., will administer the government contract and provide project oversight. SkySentry, LCC, also from Colorado Springs, will furnish the aerostat, crew training and supervisory staff. The Ohio Aerospace Institute in Cleveland, Ohio, will manage research and development efforts. -end-
