Exhibit 99.1

ENVIRONMENTAL TECTONICS CORPORATION

AMEX Hearing Scheduled

     Southampton, PA, March 4, 2008 — Environmental Tectonics Corporation (AMEX: ETC) (the “Company”) today reported that, on February 29, 2008, AMEX had granted the Company’s request for an oral hearing to review the determination of AMEX to delist the Company’s common stock from listing and registration on AMEX. The hearing is scheduled for April 9, 2008. The Company has the option of submitting by March 24, 2008 written materials in support of the continued listing of the Company’s common stock.

     This hearing results from a request by the Company to appeal a decision made by the AMEX on January 30, 2008 to initiate delisting proceedings of the Company’s common stock. As a result of the Company’s failure to file its Quarterly Reports on Form 10-Q for (i) the first fiscal quarter ended May 25, 2007, (ii) the second fiscal quarter ended August 24, 2007, and (iii) the third fiscal quarter ended November 23, 2007, the Company is not in compliance with Sections 134 and 1101 of the AMEX Company Guide. This non-compliance by the Company made the Company’s common stock subject to being delisted from AMEX.

     The Company may submit written materials and intends to make a presentation at the hearing in support of the continued listing of the Company’s common stock on AMEX but there is no assurance that the Company’s request for continued listing on AMEX will be granted. If the Listing Qualifications Panel of the AMEX Committee on Securities does not grant the relief requested by the Company, its common stock will be delisted from AMEX. If the Company’s common stock is delisted, the Company expects that its common stock would be quoted on the Over-The-Counter Bulletin Board if the Company is current in its filings with the Securities and Exchange Commission. Otherwise, it is expected that the Company’s common stock would be quoted on the Pink Sheets.

     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.
