Exhibit 99.1

                                  Risk Factors

     You should consider the following risks carefully in evaluating us and our
business before making an investment decision. The risks described below are not
the only risks we face. Additional risks may also impair our business
operations. If any of the following risks occur, our business, results of
operations or financial condition could be materially adversely affected. If
that happens, the trading price of our common shares could decline, and you may
lose all or part of your investment.

                          Risks related to our business

We depend on government contracts for most of our revenues.

     We are a supplier, either directly or as a subcontractor, to the U.S.
government and its agencies, principally the U.S. Air Force. All of our revenues
for 2002 and 92% of our revenues for 2001 were derived from government contract
sales. One of our contracts, for the T-38 "Talon", accounted for 29.5% of our
revenue for 2002. We depend on these government contracts for most of our
business. If we are suspended or debarred from contracting with the U.S.
government, if our reputation or relationship with individual federal agencies
were impaired, or if the government otherwise ceased doing business with us or
significantly decreased the amount of business it does with us, our business,
prospects, financial condition and operating results would be materially
adversely affected.

We face risks relating to government contracts.

     There are inherent risks in contracting with the U.S. government, including
risks that are peculiar to the defense industry, which could have a material
adverse effect on our business, prospects, financial condition and operating
results. All contracts with the U.S. government contain provisions and are
subject to laws and regulations that give the government rights and remedies not
typically found in commercial contracts, including rights that allow the
government to: o terminate contracts for convenience in whole or in part at any
time;

o    reduce or modify contracts or subcontracts if its requirements or budgetary
     constraints change;

o    cancel multi-year contracts and related orders if funds for contract
     performance for any subsequent year become unavailable;

o    adjust contract costs and fees on the basis of audits completed by its
     agencies;

o    claim rights in products and systems produced by us;

o    suspend or debar us from doing business with U.S. government; and

o    control or prohibit the export of our products.

     If the U.S. government terminates a contract for convenience, we may
recover only our incurred or committed costs, settlement expenses and profit on
work completed prior to the termination. If the government terminates a contract
for default, we may not recover even those amounts, and instead may be liable
for excess costs incurred by the government in procuring undelivered items and
services from another source.

We have risks associated with competing in the bidding process for U.S.
government contracts.

     We obtain many of our U.S. government contracts through a competitive
bidding process. In the bid process,
we face the following risks:

o    We must bid on programs in advance of their completion, which may result in
     unforeseen technological difficulties or cost overruns;

o    We must devote substantial time and effort to prepare bids and proposals
     for competitively awarded contracts that may not be awarded to us; and

o    Awarded contracts may not generate sales sufficient to result in
     profitability.

We are subject to strict governmental regulations relating to the environment
which could result in fines and remediation expense in the event of
non-compliance.

     We are required to comply with extensive and frequently changing
environmental regulations at the federal, state and local levels. Among other
things, these regulatory bodies impose restrictions to control air, soil and
water pollution, to protect against occupational exposure to chemicals,
including health and safety risks, and to require notification or reporting of
the storage, use and release of certain hazardous substances into the
environment. This extensive regulatory framework imposes significant compliance
burdens and risks on us. In addition, these regulations may impose liability for
the cost of removal or remediation of certain hazardous substances released on
or in our facilities without regard to whether we knew of, or caused, the
release of such substances. Furthermore, we are required to provide a place of
employment that is free from recognized and preventable hazards that are likely
to cause serious physical harm to employees, provide notice to employees
regarding the presence of hazardous chemicals and to train employees in the use
of such substances. Our operations require the use of a limited amount of
chemicals and other materials for painting and cleaning that are classified
under applicable laws as hazardous chemicals and substances. If we are found not
to be in compliance with any of these rules, regulations or permits, we may be
subject to fines, remediation expenses and the obligation to change our business
practice, any of which could result in substantial costs that would adversely
impact our business operations and financial condition.

We may be subject to fines and disqualification for non-compliance with Federal
Aviation Administration regulations.

     We are subject to regulation by the Federal Aviation Administration under
the provisions of the Federal Aviation Act of 1958, as amended. The FAA
prescribes standards and licensing requirements for aircraft and aircraft
components. We are subject to inspections by the FAA and may be subjected to
fines and other penalties (including orders to cease production) for
noncompliance with FAA regulations. Our failure to comply with applicable
regulations could result in the termination of or our disqualification from some
of our contracts, which could have a material adverse effect on our operations.

We had a shareholders' deficit and working capital deficit for December 31,
2001.

     At December 31, 2001, we had a shareholders' deficit (i.e., the amount by
which liabilities exceed assets) of approximately $2.3 million. We also had
negative working capital (the amount by which current liabilities exceed current
assets) of $2,807,657 at December 31, 2001. These types of deficits indicate
that we may not be able to pay our debts as they become due. There can be no
assurance that we will not experience such deficits again in the future.

If the contracts associated with our backlog were terminated, our financial
condition would be adversely affected.

     The maximum contract value specified under each government contract
that we enter into is not necessarily indicative of the revenues that we will
realize under that contract. Because we may not receive the full amount we
expect under a contract, we may not accurately estimate our backlog because the
actual accrual of revenues on programs included in backlog may never occur or
may change. Cancellations of pending contracts or terminations or reductions of
contracts in progress could have a material adverse effect on our business,
prospects, financial condition or results of operations. As of December 31,
2002, our backlog was $70,735,023, of which 27% was funded and 73% was unfunded.

We may be unable to retain personnel who are key to our operations.

     Our success, among other things, is dependent on our ability to attract and
retain highly qualified senior officers and engineers. Competition for key
personnel is intense. Our ability to attract and retain senior officers and
experienced, top rate engineers is dependent on a number of factors, including
prevailing market conditions and compensation packages offered by companies
competing for the same talent. The inability to hire and retain these persons
may adversely affect our production operations and other aspects of our
business.

We may have committed a violation of the securities laws that would allow
investors in our recent public offering the right to rescind and demand the
return of their purchase price.

     On February 19, 2003, we consummated a public offering of 2,300,000 of our
common shares at a price of $4.00 per share raising gross proceeds of
$9,200,000. Prior to the consummation of the offering, some of our officers were
interviewed by a reporter and an article about our company was subsequently
published in a newspaper. It is possible that our officers' participation in the
interview combined with the publication of the article may be considered a
violation of Section 5 of the Securities Act. If investors in the offering were
to sue us and convince a court that we violated Section 5, they would have the
right under the federal securities laws to rescind their purchases of common
shares for a period of one year from the date of the violation. Alternatively,
if the investors already sold their shares they would have the right to receive
damages to the extent the price they paid us for the common shares exceeded the
price at which they sold them. Accordingly, we might be required to return to
certain investors all or part of their purchase price and the net proceeds from
the offering to us would be correspondingly reduced.
