ENVIRONMENTAL TECTONICS CORPORATION - Press Release
Environmental Tectonics Corporation Announces Shipment of the First G-FET II / ATFS-400
October 15, 2004
Southampton, PA: October 15, 2004-Environmental Tectonics Corporation (Amex: ETC) ("ETC" or "the Company") today announced shipment of the first G-FET II equipped as an Authentic Tactical Flight Simulator (Model ATFS-400).

Shipment of the G-FET II / ATFS-400 follows successful completion of a comprehensive Acceptance Testing process, involving customer experts, that was conducted at ETC's manufacturing plant in Southampton, PA. ETC is the only centrifuge manufacturer in the world that has the ability to design, build and test in-house. Field engineers are now installing the G-FET II at the customer's site. After installation, Acceptance Testing will be repeated to insure complete customer satisfaction as well as system safety and reliability.

Over the past twelve years, ETC has developed and manufactured the G-FET II, a project that has produced the world's most advanced high performance human centrifuge. Over the past five years, ETC has integrated full Tactical Flight Simulation into the G-FET II to produce the G-FET II / ATFS-400. The G-FET II / ATFS-400 combines the latest available flight simulation technology to optimize flight fidelity. This technology includes high fidelity aircraft specific cockpits, offensive and defensive mission systems, realistic wide field of view visual displays and virtual battle space. Additionally, the G-FET II / ATFS-400 provides the proprietary ETC technology of G-pointing that provides the pilot with the same sustained G that he experiences during actual combat maneuvering.

ETC's breakthrough technology allows a pilot to hone critical air combat skills in a safe and economical environment at 1/20th the cost of flying in the aircraft. Savings include reduced fuel consumption and reduced aircraft wear. Even greater savings are realized through lowered accident rates since the pilot can rehearse an aircraft mission in the G-FET II / ATFS-400 before actual flight. Over 150 experienced fighter pilots have "flown" the G-FET II / ATFS-400 to date and the consensus is that it is the most authentic simulator currently available.

William F. Mitchell, ETC's President and Chairman, stated, "ETC is engaged in an aggressive campaign to present the ATFS-400 technology to the U.S. Congress and the U.S. DoD at the highest levels. Based on those efforts to date, ETC is confident there is growing support for the notion that the expanded use of simulation and synthetic experience is an important element to consider in our efforts to transform the way the U.S. sustains defense readiness. The ATFS-400 is a developed technology that is ready to be put to use today to improve readiness, reduce costs, and save lives."

ETC designs, develops, installs and maintains aircrew training systems, public entertainment systems, process simulation systems (sterilization and environmental), clinical hyperbaric systems, environmental testing and simulation systems, and related products for domestic and international customers.
