                       ENVIRONMENTAL TECTONICS CORPORATION
                   ANNOUNCES THIRD QUARTER FISCAL 2005 RESULTS


Southampton, PA: January 11, 2005 - ENVIRONMENTAL TECTONICS CORPORATION ("THE
COMPANY") (AMEX: ETC) today announced financial results for the third quarter of
fiscal 2005.

         For the third quarter of fiscal 2005, which ended on November 26, 2004,
the Company had a net loss of $3,249,000, or ($0.43) per share (diluted), versus
a net loss of $704,000 or ($0.10) per share (diluted) for the third quarter of
fiscal 2004. Sales for the third quarter of fiscal 2005 were $7,751,000, as
compared to $7,115,000 for the third quarter of fiscal 2004, an increase of
$636,000 or 8.9%, reflecting sales increases in the environmental, hyperbaric
and entertainment lines. Environmental benefited from higher international sales
primarily in Italy. Hyperbaric, which evidenced the most significant increase
(domestic hyperbaric sales were up $940,000) benefited from the production on
two large multi-man hyperbaric chambers. Entertainment benefited from work on
Wild Earth(TM) units being produced for the Philadelphia Zoo.

         Geographically, domestic sales for the third quarter of fiscal 2005
were $3,318,000, up $543,000 or 19.6% from the third quarter of fiscal 2004,
reflecting increases in hyperbaric, service and entertainment sales. Hyperbaric
and entertainment sales benefited from the aforementioned activity while service
benefited from work on domestic sterilizers. Domestic sales represented 42.8% of
the Company's total sales for the third quarter of fiscal 2005, up from 39.0%
for the third quarter of fiscal 2004. U.S. Government sales for the third
quarter of fiscal 2005 were $1,157,000 as compared to a negligible amount in the
third quarter of fiscal 2004. International sales for the third quarter of
fiscal 2005, including those made by the Company's foreign subsidiaries, were
$3,276,000, a decrease of $1,106,000 or 25.2% from international sales for the
third quarter of fiscal 2004, and represented 42.3% of total sales for the third
quarter of fiscal 2005 as compared to 61.6% for the third quarter of fiscal
2004.

         Gross profit for the third quarter of fiscal 2005 was $1,637,000, as
compared to $1,774,000 for the third quarter of fiscal 2004, a decrease of
$137,000 or 7.7%. This decrease resulted from a 3.8 percentage point decrease in
the gross profit rate as a percent of sales partially offset by an increase in
sales volume. The quarter-to-quarter reduction reflected reduced manufacturing
performance in all groups except hyperbaric (on favorable costing for the
aforementioned large chamber contracts) and ATS which benefited from a large
multi-product contract sold through the U.S. government. Acting as partial
offsets were a reduction in sterilizers which benefited in the prior period from
a large multi-unit contract and continued cost overruns in the environmental
group.

         Selling and Administrative Expenses for the third quarter of fiscal
2005 were up $1,894,000 from the third quarter of fiscal 2004 primarily
reflecting significantly higher costs associated with litigation and the
Company's ongoing contract claims activities.

         William F. Mitchell, ETC's President and Chairman, stated, "The world
market for our main product line of Aircrew Training Systems continued to be
tight during the third quarter, although there were some definite positive signs
that some major contracts, especially internationally, may be awarded by year
end. An indication of this is the recent booking of approximately $1 million for
monoplace chambers for Japan. Additionally, we have preliminary information that
an additional approximate $5 million of new orders will soon be awarded to ETC.
Another very large international contract for multiple aeromedical equipment is
expected to be let for final bid in the near future. Although these contracts
will not have a significant impact on sales for the fourth quarter, they will
obviously strengthen our opening order backlog for the new year.

         "Our entertainment subsidiary (EnTCo) was recently honored with two
significant awards at the International Association of Amusement Parks and
Attractions (IAAPA), the premiere trade show for the amusement industry. Our
Wild Earth(TM) ride was deemed "Best New Product" and our booth also captured
the "Best Exhibit" award for booths in our size category. Our entertainment
group has booked almost $1.9 million in new orders this year including two rides
for Jeepers! Family Entertainment Centers in New Jersey and New York. We
recently agreed to collaborate with the National Oceanic and Atmospheric
Administration's National Marine Sanctuary Program (NMSP) to combine the NMSP's
subject-matter expertise and mission with EnTCo's education simulation
technology.

         "Our environmental business continued strong in the quarter, although
profits continue to elude this group. Entering the highly competitive Chinese
automotive market has proven to be much more costly and logistically difficult
than originally planned.

         "An extremely exciting new market area was opened up in October with
the success of SpaceShipOne's successful two sub orbital flights in less than
two weeks. ETC is perfectly positioned to capitalize on providing both hardware
and training for citizen space travelers. Our vast product line of G-force,
spatial disorientation and flight training products are all capable of providing
professional support for the gamut of space experience and provide all levels of
solutions for those who want to experience the ultimate space adventure. The

         "On November 16, 2004, ETC's sterilizer group was awarded patent
approval for our revolutionary "One-Step" sterilization process. This process
combines sterilization and drying of pharmaceutical products into one
application, thereby reducing the entire sterilization cycle per lot by 5 to 7
hours, reducing labor cost, time and product damage, and eliminating the cost of
drying ovens. This new process will greatly benefit companies that process
bagged stoppers, caps and line seals.

         "In September, 2004, Our Polish subsidiary ETC-PZL concluded
negotiations with L-3 Communications to assemble, test and deliver several L-3
designed simulators as well as furnish ETC-PZL's own commercial cockpit
simulators to the Polish Air Force.

         "Although it has continued to be a difficult year for new contracts, I
can assure you that we are doing everything possible to expand our book of
business."

         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.
