                              EMPLOYMENT AGREEMENT

      This Employment Agreement between World Airways, Inc., a Delaware
corporation ("World" or the "Company") and CHARLES P. MCDONALD ("McDonald") is
entered into this 3RD day of MAY 2004.

      WHEREAS, MCDONALD has agreed to serve as World's SENIOR VICE PRESIDENT
OPERATIONS as of MAY 3, 2004.

      NOW, THEREFORE, World and MCDONALD, in consideration of the foregoing and
other mutual covenants and promises contained herein, the sufficiency of which
are hereby acknowledged, hereby agree as follows:

      1. ACCEPTANCE OF EMPLOYMENT. Subject to the terms and conditions set forth
below, World agrees to employ MCDONALD and MCDONALD accepts such employment.

      2. TERM. The period of employment shall be from MAY 3, 2004, THROUGH MAY
6, 2007, unless further extended or sooner terminated as hereinafter set forth.
In the absence of notice, this Agreement shall be renewed on the same terms and
conditions for one year from the date of expiration. Not later than OCTOBER 6,
2006, MCDONALD shall initiate discussions with the Chief Executive Officer
(hereinafter "CEO") regarding the renewal of this Agreement. At that time, if
MCDONALD wishes to renew this Agreement on different terms, MCDONALD shall give
written notice to the CEO. If the CEO does not wish to renew this Agreement at
its expiration, or wishes to renew on different terms, the CEO shall give
written notice to MCDONALD no later than NOVEMBER 6, 2006

      3. POSITION AND DUTIES. MCDONALD shall serve as SENIOR VICE PRESIDENT OF
OPERATIONS with duties performed as of the date hereof, as those duties may be
changed from time to time. The CEO will have reasonable latitude to make changes
in MCDONALD'S responsibilities, except that MCDONALD'S responsibilities may not
be modified in a way that would be inconsistent with the status of SENIOR VICE
PRESIDENT OF

<PAGE>

OPERATIONS. Following a Change of Control (as hereinafter defined), MCDONALD'S
responsibilities may not be changed without mutual agreement. MCDONALD agrees to
render his services to the best of his abilities and will comply with all
policies, rules and regulations of the company and will advance and promote to
the best of his ability the business and welfare of the Company. MCDONALD shall
devote all of his working time, attention, knowledge and skills solely to the
business and interests of World. MCDONALD may not accept any other engagement
with or without compensation, which would affect his ability to devote all of
his working time and attention to the business and affairs of World without the
prior written approval of the CEO. MCDONALD agrees to accept assignments on
behalf of World or affiliated companies commensurate with his responsibilities
hereunder, except that the terms and conditions of assignments exceeding 60
consecutive days outside the ATLANTA, GEORGIA Standard Metropolitan Statistical
Area will require mutual agreement.

      4. COMPENSATION AND RELATED MATTERS.

      (a) BASE SALARY. MCDONALD shall receive a minimum salary of $170,000 per
annum payable in accordance with the payroll procedures for World's salaried
employees in effect during the term of this Agreement. MCDONALD agrees to
participate equally, on a percentage basis, in any across the board salary
reductions approved by senior management.

      (b) PERFORMANCE STOCK OPTIONS. MCDONALD has been granted 100,000 OPTIONS
to purchase World's Common Stock, par value $.001 per share ("World Airways
Common Stock") pursuant to the World Airways, Inc. Amended and Restated 1995
Stock Incentive Plan (the "Plan") as set forth in the Stock Option Agreement
between World and McDonald dated MAY 6, 2004 (the "Option Agreement"). In the
event of a Change in Control as defined below, all Options shall be immediately
exercisable.

      (c) BUSINESS EXPENSES. MCDONALD shall be entitled to reimbursement of
reasonable business related expenses from time to time consistent with World's
policies, including, without limitation, submitting in a timely manner
appropriate documentation of such expenses.

<PAGE>

      (d) FRINGE BENEFITS. MCDONALD shall be entitled to participate in all
employee benefit plans made available from time to time to all executives of
World in accordance with the terms of such plans. In the event this Agreement is
terminated by either party for any reason other than death or for cause,
MCDONALD may participate in World's health and other benefit programs for a
period of one year from the date of MCDONALD'S termination, or until MCDONALD
obtains comparable coverage, whichever is earlier.

      (e) PERSONNEL POLICIES, CONDITIONS AND BENEFITS. Except as otherwise
provided herein, MCDONALD'S employment shall be subject to the personnel
policies and benefits plans which apply generally to World's employees as the
same may be interpreted, adopted, revised or deleted from time to time, during
the term of this Agreement, by World in its sole discretion. While this
Agreement is in effect, MCDONALD shall receive twenty (20) DAYS of vacation, in
addition to sick leave, holidays, and such other leave as World may provide. All
such vacation and leave shall be taken in accordance with the Company's
procedures.

      (f) INDEMNIFICATION; D&O INSURANCE. Subject to Section 6(b) of this
Agreement, World shall provide (or cause to be provided) to MCDONALD
indemnification against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlements in connection with any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (including an action by or in the right of World) by reason of
his being or having been an officer, director or employee of World or any
affiliated entity, advance expenses (including attorneys' fees) incurred by
MCDONALD in defending any such civil, criminal, administrative or investigative
action, suit or proceeding and maintain directors' and officers' liability
insurance coverage (including coverage for securities-related claims) upon
substantially the same terms and conditions as set forth in the INDEMNIFICATION
AGREEMENT dated MAY 3, 2004, between MCDONALD and World Airways, Inc. (the
"Indemnity Agreement").

      5. TERMINATION OF EMPLOYMENT.

      (a) DEATH. MCDONALD'S employment hereunder shall terminate upon his death,
in which event World shall have no further obligation to MCDONALD or his estate
with respect to compensation, other than the disposition of life insurance and
related benefits

<PAGE>

and accrued and unpaid base salary and incentive compensation, if any, for
periods prior to the date of termination pursuant to the terms of the respective
employee benefits and incentive compensation plans then in effect.

      (b) BY WORLD FOR DISABILITY. If MCDONALD is unable, or fails, to perform
services pursuant to this agreement through illness or physical or mental
disability and such failure or disability shall exist for twelve (12)
consecutive months, then World may terminate this Agreement upon written notice
to MCDONALD, in which event World shall have no obligation to MCDONALD with
respect to compensation under Section 4(a) of this Agreement. If MCDONALD
becomes entitled to Social Security benefits payable on account of disability,
he will be deemed conclusively to be disabled for purposes of this Agreement.

      (c) BY WORLD FOR CAUSE.

            (i) Except under the circumstances set forth in 5(c)(ii) below, the
            CEO may terminate this Agreement for Cause. "Cause" shall be defined
            as (A) sustained performance deficiencies which are communicated to
            MCDONALD in written performance appraisals and/or other written
            communications (including, but not limited to memos and/or letters)
            by the CEO, (B) gross misconduct, including significant acts or
            omissions constituting dishonesty, intentional wrongdoing or
            malfeasance, whether or not relating to the business of World, or
            (C) commission of a felony or any crime involving fraud or
            dishonesty, or (D) a material breach of this Agreement.

            (ii) In the event of a Change of Control, as defined below, MCDONALD
            may only be terminated for Cause pursuant to a resolution duly
            adopted by the affirmative vote of a majority of the entire
            membership of the Board, at a meeting of the Board finding that, in
            the good faith opinion of the Board, MCDONALD was guilty of conduct
            set forth in 5(c)(i)(A), or (B), provided, however, that MCDONALD
            may not be terminated for Cause hereunder unless: (1) MCDONALD
            receives prior written notice of World's intention to terminate this
            Agreement for Cause and the specific reasons therefore; and

<PAGE>

            (2) MCDONALD has an opportunity to be heard by World's Board and be
            given, if the acts are correctable, a reasonable opportunity to
            correct the act or acts (or non-action) giving rise to such written
            notice. If the Board, by resolution duly adopted by the affirmative
            vote of a majority of the entire membership of the Board, finds that
            MCDONALD fails to make such correction after reasonable opportunity
            to do so, this Agreement may be terminated for Cause.

      (d) BY WORLD FOR OTHER THAN CAUSE. In the event the Board terminates this
Agreement for reasons other than Cause or Disability as defined in sub-paragraph
(c) above, World will pay to MCDONALD within ten (10) days of notice of
termination (or, in the case of incentive bonus compensation, if any, within ten
(10) days of determination of amounts payable under the applicable bonus plan)
twelve months base salary, in each case including deferred salary and/or bonus
compensation, if any, payable under this Agreement. In addition, all granted but
unvested Options under the Option Agreements shall become immediately
exercisable. In the event that any payment to MCDONALD under this paragraph is
subject to any federal or state excise tax, World shall pay to MCDONALD an
additional amount equal to the excise tax imposed including additional federal
and state income and excise taxes as a result of the payments under this
paragraph, and such payment will be made when the excise tax and income taxes
are due; provided, however, that MCDONALD agrees to assist World Airways by
using his best efforts to structure matters so that any payment to MCDONALD
under this paragraph is not subject to any federal or state excise tax. Whether
an excise tax is payable, and the amount of the excise tax and additional income
taxes payable, shall be determined by World's accountants and World shall hold
MCDONALD harmless from any and all taxes, penalties, and interest that may
become due as a result of the failure to properly determine that an excise tax
is payable or the correct amount of the excise tax and additional income taxes,
together with all legal and accounting fees reasonably incurred by MCDONALD in
connection with any dispute with any taxing authority with respect to such
determinations and/or payments.

      (e) BY MCDONALD FOR GOOD REASON. MCDONALD may terminate his employment
hereunder (for purposes of this Agreement "Good Reason") after giving at least
30 days notice in the event that, without MCDONALD'S consent, (i) World
relocates its general and

<PAGE>

administrative offices or MCDONALD'S place of employment to an area other than
the Atlanta, Georgia Standard Metropolitan Statistical Area, (ii) he is assigned
any duties substantially inconsistent with Section 3 hereof, (iii) World reduces
his annual base salary as in effect on the date hereof or as the same may be
increased from time to time, except as provided in Section 4(a) above; (iv)
World fails, without MCDONALD'S consent, to pay MCDONALD any portion of his
current compensation, or to pay him any portion of an installment of deferred
compensation under any deferred compensation program of World, within seven (7)
days of the date such compensation is due; (v) World fails to continue in effect
any compensation plan in which McDonald participates which is material to
MCDONALD'S total compensation, unless an equitable arrangement (embodied in an
ongoing substitute or alternative plan) has been made with respect to such plan,
or to continue MCDONALD'S participation therein (or in such substitute or
alternative Plan) on a basis not materially less favorable, both in terms of the
amount of benefits provided and the level of MCDONALD'S participation relative
to other participants; (vi) World fails to continue to provide MCDONALD with
benefits substantially similar to those enjoyed by MCDONALD under any of World's
pension, life insurance, medical, health and accident, or disability plans in
which MCDONALD was participating, World takes any action which would directly or
indirectly materially reduce any of such benefits or deprive MCDONALD of any
material fringe benefit enjoyed by MCDONALD; (vii) World terminates, or proposes
to terminate, MCDONALD'S employment hereunder contrary to the requirements of
Section 5(c) hereof (for purposes of this Agreement, no such termination or
purported termination shall be effective); or, with or without MCDONALD'S
consent (viii) the Board approves the liquidation or dissolution or Change of
Control of World prior to the end of this Agreement. In the event that MCDONALD
decides to terminate this Agreement and his employment with World or any
successor in interest in accordance with the provisions of this Section 5(e),
World shall have the same obligations as set forth in Section 5(d) hereof. Any
other payments due or actions required under this paragraph shall be made as
lump sums or taken within 10 days of termination of the Agreement.

      (f) BY MCDONALD FOR OTHER THAN GOOD REASON. Notwithstanding the above,
MCDONALD may upon giving reasonable notice, not to be less than 30 days,
terminate this Agreement without further obligation on the part of MCDONALD or
World.

provisions of this Agreement or to exercise any remedy, option, right, power or
privilege provided for herein, or to require the performance by the other party
of any of the provisions hereof, shall in no way be deemed a waiver of such
provision at the same or at any prior or subsequent time.

application and interpretation of this Agreement shall be governed by and
construed in accordance with the laws of the STATE OF GEORGIA without giving

jurisdiction) that would cause the application of the law of any jurisdiction
other than GEORGIA. MCDONALD agrees to submit to personal jurisdiction in the
STATE OF GEORGIA.
