Our principal sales executive is our President, who maintains regular contact with the largest customers and continually seeks to develop new customers. We do not currently employ the services of manufacturer's representatives or sales personnel. O and S Research, Inc. and our products are listed in the Thomas Register. We also maintain sales websites at osresearch.com and optsciences.com. We engage in a low cost public relations and advertising program. Purchasing personnel of corporations or governmental agencies place orders with us, based on price, delivery terms, satisfaction of technical specifications and quality of product. Procurement departments of customers ordinarily purchase products from us because we are on an approved vendor list. We enhance sales prospects by providing creative technical solutions to customer requirements. We are currently an approved vendor for major aircraft programs. We continue to be a major supplier for the antiglare face plates covering the flat panel displays on the Boeing 777 and the 737 Next Generation models of commercial aircraft and the long range Gulfstream and Dassault Falcon business jets. We are also an approved vendor for instrument glass used on several military aircraft platforms including the C5 Galaxy and the C130. We derived approximately 65% of our revenues from two major customers and two subcontractors of one of those customers. The loss or permanent curtailment of business with either of these companies would have a negative impact on our operating results.
