Exhibit 99.1

ENVIRONMENTAL TECTONICS CORPORATION
REPORTS RECEIPT OF NON-COMPLIANCE NOTICE FROM AMEX

Southampton, PA, July 9, 2008 — Environmental Tectonics Corporation (AMEX: ETC) (“ETC” or the “Company”) today announced that on July 2, 2008, it had received a letter from the American Stock Exchange (“AMEX”) stating that the Company was not in compliance with Section 1003 of the AMEX Company Guide. Specifically, the Company is not in compliance with Section 1003(a)(i) of the AMEX Company Guide with stockholders’ equity of less than $2,000,000 and losses from continuing operations and net losses in two out of its three most recent fiscal years, Section 1003(a)(ii) of the AMEX Company Guide with stockholders’ equity of less than $4,000,000 and losses from continuing operations and net losses in three out of its four most recent fiscal years, and Section 1003(a)(iii) of the AMEX Company Guide with stockholders’ equity of less than $6,000,000 and net losses in its five most recent fiscal years.

The non-compliance by the Company with Section 1003 of the AMEX Company Guide makes the Company’s common stock subject to being delisted from AMEX. The Company is required to submit a plan to AMEX by August 1, 2008 advising AMEX of the actions that it intends to take to bring the Company into compliance with the continued listing standards set forth in the AMEX Company Guide by January 4, 2010. The Company intends to submit a plan to bring the Company back into compliance with such continued listing standards by such date. There can be no assurance that AMEX will accept the Company’s plan for compliance or, if accepted, that the plan will be implemented by January 4, 2010.

As a consequence of falling below the continued listing standards of the AMEX Company Guide, the Company will be included in a list of issuers that are not in compliance with AMEX’s continued listing standards. Additionally, an indicator will be added to the Company’s trading symbol noting the Company’s non-compliance with the continued listing standards of the AMEX Company Guide until such time as the Company regains compliance with the applicable listing standards.

On July 2, 2008, the Company also received a letter from AMEX stating that the Company had resolved the prior continued listing deficiencies referenced in letters received by the Company from AMEX dated July 17, 2007 and October 18, 2007 as a result of the failure by the Company to file certain reports with the Securities and Exchange Commission.

ETC designs, develops, installs and maintains aircrew training systems (aeromedical, tactical combat and general), disaster management training systems and services, entertainment products, sterilizers (steam and gas), environmental testing products, hyperbaric chambers and related products for domestic and international customers.
