May 2, 1997 - Eidetics Corporation was awarded a contract to provide a wind tunnel rotary balance rig and Eidetics' water tunnel model 2436 to Hyosung Industries Co. Ltd., Seoul, Republic of Korea. These systems will be used by the Korean Agency for Defense Development's Low Speed Wind Tunnel Project. The contracting organization, Hyosung Industries Co.
