ENVIRONMENTAL TECTONICS CORPORATION - Press Release
ETC Announces Realistic Dogfights will Demonstrate Revolutionary New Authentic Tactical Flight Simulation Technology during Exercise ORANGE FLAG
January 13, 2004
With hands-on competitive engagements -- experienced combat pilots will assess the most recent technology to support Tactical Aviation -- the Authentic Tactical Flight Simulator (ATFS 400)

SOUTHAMPTON, Pa., January 13, 2004-Environmental Tectonics Corporation [AMEX:ETC] will showcase the next generation in true-fidelity air combat simulation technology - the world's first Authentic Tactical Flight Simulator for high performance aircraft (ATFS 400) - at its corporate headquarters in Southampton, Pa. ATFS 400 is a centrifuge-based simulator that includes authentic G-forces matching the dynamic aircraft response in tactical air maneuvers.

Exercise ORANGE FLAG, hosted by ETC from 19 January 2004 through 23 January 2004, is a weeklong series of "free-play" air-to-air competitive combat engagements between the centrifuge-based simulator Authentic Tactical Flight Simulator (ATFS 400) and a comparably configured fixed-base non-motion Operational Flight Simulator (OFS 400). During ORANGE FLAG, experienced pilots from allied nations and the U.S. tactical air forces (U.S. Air Force, U.S. Navy and U.S. Marine Corps) will fly the ATFS 400 and the OFS 400, configured as either a MIG 29 or an F/A-18 "Hornet" against each other to objectively demonstrate to pilots and observers the authenticity of tactical maneuvering experience provided by the ATFS 400 technology. Flying both simulators, the experienced pilots can assess the value of the ATFS technology. Integrating authentic physical forces with high fidelity simulated tactical elements, the ATFS 400 immerses tactical pilots and aircrews in a more effective and economic learning environment than non-motion simulator or airborne training alone. Physical and tactical decision stresses closely correspond to those experienced in actual combat tactical engagements. Authentic G-forces and interactive threats provide a realistic fully stressed fighting situation -- in a safe, controlled environment, at a much lower cost than flying operational aircraft. With ATFS, risk is eliminated, access time increased, aircraft service life is extended and the chaos of air combat more authentically simulated.

William F. Mitchell, ETC's President and Chairman, commented, "Fully utilized, the ATFS can save the U.S. government billions of dollars through reduction of operating costs, aircraft mishap risk, wear-out of tactical aircraft and systems - and expensive tactical range operational cost"
