ENVIRONMENTAL TECTONICS CORPORATION - Press Release
ETC Announces Their Human Centrifuge Trains the 25,000th Pilot at Holloman Air Force Base, NM
August 11, 2004
SOUTHAMPTON, Pa., Aug. 11 /PRNewswire-FirstCall/ -- Environmental Tectonics Corporation (Amex: ETC) announced today that Holloman AFB, located in New Mexico, has completed the training of the 25,000th pilot on its G- LAB(R) Human Centrifuge.

The USAF achieved an unprecedented milestone, training their 25,000th student in the G-LAB high-performance human centrifuge on August 10, 2004. Celebration activities took place at the Holloman Air Force Base Physiology Training Unit (PTU) to acknowledge this landmark accomplishment.

The USAF selected the ETC G-LAB in 1988 and during the past 16 years, the G-LAB has been the primary centrifuge for the United States Air Force High-G training program. G-LAB training has been responsible for reducing the number of G-induced Loss of Consciousness (G-LOC) mishaps (both Class A and C) by more than fifty percent.

The United States Air Force Centrifuge Training Program is one of the most aggressive training programs in the world. In addition to training U.S. pilots on the G-LAB, the Air Force Physiology Training unit has trained pilots from Canada, Japan, Korea, Israel, Jordan, Bahrain, Pakistan, Australia, Poland, Italy, Taiwan, Singapore, Chile, United Kingdom, Sweden, Switzerland, Czechoslovakia, Egypt, Finland, Germany, Turkey, Kuwait, Saudi Arabia, and others.

G-LOC and High-G unusual attitude conditions are a constant threat to the aircrew of high-performance fighter and attack aircraft. These dangers will become even greater in the future, as high airspeeds, low altitude, and super maneuverability of modern aircraft will place even greater demands on the physical capabilities of pilots. G-tolerance training and dynamic flight simulation, using High G-onset centrifuges, are the most effective ways to increase aircrew G-tolerance and train aircrews in new recovery techniques and High-G spatial orientation.

ETC, the world leader in human centrifuge design and manufacture, has provided Aircrew Training Systems and Flight Trainers to military and civil agencies worldwide for nearly 35 years.

William F. Mitchell, ETC's President & CEO, attended the Holloman AFB celebration and noted, "The G-LAB has been a workhorse for the Air Force for over 16 years, and continues to reflect the high level of quality that ETC puts into the design, manufacture and long-term maintenance of its products. Today, the G-LAB is distinguished as the most heavily used training centrifuge in the world. Thanks to the dedicated efforts of the ETC staff and our on- site manager, Mr. Steve Arnold, the G-LAB has also set world records for the highest in service rate (greater than 99%) throughout the past 16 years. The USAF continues to set the world standard for High G training and ETC is proud to be a part of this very important program."

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.
