ETC Receives Follow-On Contract for TACModule

Southampton, PA: September 4, 2007 - Environmental Tectonics Corporation (AMEX: ETC) ("ETC" or the "Company") today announced the award of a contract to produce a Sukhoi Su-30 Tactical Aircraft Configuration Module (TACModule™) for a Southeast Asian customer, bringing the total number of TACModules supplied by ETC to this customer to four.

The sole source contract, with a total value of over $1.2 million, will produce a TACModule in the Su-30 configuration. This TACModule will be used to support tactical flight training for Su-30 pilots in the customer's Authentic Tactical Fighting System - 400 (ATFS-400™), which was delivered by ETC in 2005.

The Su-30 TACModule contract brings the number of TACModules that have either been supplied by ETC or are currently on contract to eight. ETC supplied three TACModules to the Southeast Asian customer with the ATFS-400 delivery in the F-18C, Mig-29N, and Hawk Mk-208 aircraft configurations. In July, ETC received a contract from the U.S. Navy to produce a TACModule in the F/A-18C configuration to support follow-on research and development as a tactical training simulator. In August, ETC received a contract from the USAF to produce a TACModule in the F-35 (Joint Strike Fighter) configuration to support tactical training research and development. Both the Navy and Air Force TacModules will be tested in the ATFS-400, located at ETC's National Aerospace Training and Research (NASTARSM) Center. Additionally, ETC has produced one TACModule in the F-15 configuration and one TACModule in a space vehicle configuration to support training and research operations at NASTAR Center.

The TACModule is a full-featured high-fidelity flight simulator, which includes a customized visual database and an aircraft-specific aeromodel. Authentic flight controls, cockpit indicators, aircrew seat and harness, and a state-of -the-art visual display place the pilot in a highly realistic environment. The ATFS-400 is the latest generation of ETC Tactical Flight Simulators and is currently operational at ETC's NASTAR Center. Using a high performance human centrifuge as a motion platform, it combines the latest available flight simulation technology to optimize flight fidelity including sustained G's.

Mr. William Mitchell, President and Chairman of ETC, stated, "The contract for the Su-30 TACModule is the embodiment of ETC's ATFS-400 concept of a rapidly reconfigurable, sustained G simulator that allows pilots to train in the most authentic tactical environment possible. The ATFS-400 is a full fidelity system that can support tactical pilot training in their specific aircraft today in; a safer training environment, at a fraction of the cost and also reduces aircraft fatigue and extends aircraft life".
