November 30, 2004
Southampton, PA-November 30, 2004- Environmental Tectonics Corporation (AMEX:ETC) ("ETC" or the "Company") today announced that its wholly owned subsidiary, Entertainment Technology Corporation (EnTCo), has received two awards, Best New Product and Best Exhibit, at the International Association of Amusement Parks and Attractions (IAAPA) Convention recently held in Orlando, Florida from November 15th to November 20th. The IAAPA Convention is the world's largest convention of its kind for Amusement Parks, Family Entertainment Centers, Zoos/Aquariums and Museums with roughly 1,200 exhibitors this year. Further information about the Awards can be found at http://www.iaapaorlando.com/prorlBestExh.htm

The Best New Product Award was granted to EnTCo for Wild Earth™, the interactive Photo Safari simulator ride. All entries were judged on the benefit of the product to the prospective buyer, the originality or uniqueness of the product, and the quality of the product's design and construction. In Wild Earth™, guests discover the thrill and excitement of an African Photo Safari experience and marvel at the array of wildlife and rich landscapes of the Serengeti. In Wild Earth™, the riders are in full control, navigating the vehicle through the stunning landscapes of Africa on a quest for that "perfect picture". Based on the award-winning game title of the same name by Super X Studios, Wild Earth™ features unparalleled graphics quality, non-violent educational content, groundbreaking interactivity and a potential tremendous revenue generator for operators. Future editions of Wild Earth™ will include "Deep Ocean Edition", "Prehistoric Edition" and "Rain Forest Edition". Further information on Wild Earth™ can be found at www.therideworks.com.

The Best Exhibit Awards are granted for the best booth presentation in each category based on booth size. Only four such awards were granted this year, out of roughly 1,200 exhibitors. The booths were judged on originality, uniqueness, promotion of product, quality of design, and professional appearance of staff.

Rob Lloyd, Creative Director of EnTCo, said "A lot of talented people in the EnTCo team worked very hard to create the Wild Earth™ attraction and it's gratifying to have that effort recognized by an organization of IAAPA's stature. We enjoy creating experiences like Wild Earth™ and it pays off when the energy EnTCo puts into development transfers to the excitement of the guests who 'volunteer' to take a ride on the wild side."
