REVOLVING CREDIT NOTE


$5,000,000                                                       August 24, 1999

     FOR VALUE  RECEIVED,  the  undersigned,  The Network  Connection,  Inc.,  a
Georgia  corporation  (the  "MAKER"),  hereby  promises  to pay to the  order of
Interactive Flight Technologies,  Inc., a Delaware  corporation,  its successors
and assigns (the "PAYEE"),  the lesser of (x) Five Million Dollars ($5,000,000),
or (y) the unpaid  principal amount of all advances made by Payee to Maker under
this  Revolving  Credit Note,  in either such case together with interest on the
outstanding principal balance thereof accrued from the date hereof calculated at
the sum of the prime lending rate (as published and changed from time to time in
the "Money Rates" section of THE WALL STREET JOURNAL, or if not so published for
any reason,  then as  published  in any other  financial  newspaper  of national
circulation) plus three percent (3%) per annum. All payments of principal and/or
interest  shall be paid in  lawful  money of the  United  States of  America  in
immediately available funds to an account designated by Payee.

     1.   FUNDING.

          Provided that no Event of Default (as such term is defined  below) has
occurred and is  continuing,  and subject to the terms and  conditions set forth
herein, commencing on the date hereof, and expiring on the day immediately prior
to the Maturity Date (as defined below), Maker may request from Payee, and Payee
shall  extend to Maker  advances  under this  Revolving  Credit  Note in amounts
requested by Maker,  provided that the amount requested,  together with all then
outstanding  advances shall not exceed,  in the aggregate,  Five Million Dollars
($5,000,000) outstanding at any one time (the "Maximum Loan Amount"). Subject to
the terms and conditions hereof,  Maker may, from time to time,  borrow,  repay,
and reborrow  advances.  All borrowings,  repayments and  reborrowings  shall be
reflected on the attached Partial Conversion Grid.

     2.   PAYMENTS OF PRINCIPAL AND INTEREST.

          (a) Interest on the  outstanding  principal  balance of this Revolving
Credit  Note shall be payable on the 5th day of each  month.  Interest  shall be
calculated  on the  basis of a 360 day year but  shall be  payable  only for the
number of days actually elapsed.

          (b) The outstanding  principal  balance of this Revolving Credit Note,
together with all accrued and unpaid interest and fees thereon, shall be due and
payable on September 30, 2001 (the "Maturity Date").

          (c) In the event that any scheduled payment date hereunder is a day on
which banks in the State of Arizona are  required  or  authorized  to be closed,
then the payment that would be due on such day shall  instead be due and payable
on the next day which is not such a non-banking  day, with  additional  interest
for such delay at the rate then in effect hereunder.

     3.   CONVERSION RIGHTS.

          Payee shall be entitled,  at any time and from time to time and in its
sole discretion, to convert all or a portion of the principal amount and accrued
interest due under this Note into shares of the Maker's  Series C 8% Convertible
Preferred Stock,  $.01 par value,  Stated Value $1,000 per share (the "PREFERRED
STOCK") or, at the option of Payee,  into the Maker's  Common Stock (the "COMMON
STOCK").  Any such conversion into Preferred Stock shall be effected at the rate
of one share of Preferred  Stock for each $1,000 due  hereunder  which Payee has
elected to convert (the "CONVERSION  RATE"). If Payee elects to convert all or a
portion  of the  principal  amount  and  accrued  interest  due under  this Note
directly  into  Common  Stock,  the  number  of  shares  to be  issued  shall be
calculated  as if such  amount  had first  been  converted  to  Preferred  Stock
hereunder  (calculated  without regard to any insufficiency of authorized shares
of Preferred  Stock) and such resulting  shares of Preferred Stock had, in turn,
immediately been converted to Common Stock at a conversion price per share equal
to the lowest of (a) $1.50, (b) 66.67% of the Current Market Price (as hereafter
defined),  (c) the price per  share at which the  Maker,  after the date of this
Revolving  Credit Note,  issues and sells any Common Stock, or (d) where coupled
with the  right of the  purchaser(s)  thereof  to  demand  that the  Corporation
register  under the  Securities  Act of 1933 any Common Shares (not  theretofore
registered)  for  which  any  warrants  or  options  may  be  exercised  or  any
convertible,  exchangeable or exercisable securities may be converted, exercised
or exchanged,  (i) the exercise  price of any such warrants or options issued by
the Maker after the date of this  Revolving  Credit Note, or (ii) the conversion
rate,  exchange rate or exercise price,  respectively,  of any such convertible,
exchangeable or exercisable  security issued by the Maker after the date of this
Revolving  Credit Note,  except for stock option  agreements or stock  incentive
agreements  issued  pursuant to employee  benefit  plans.  For  purposes of this
Paragraph  3, the term  "Current  Market  Price"  means the closing bid price as
reported on the Nasdaq Stock  Market (or if not then traded on such  market,  on
such  exchange or  quotation  system  where such shares are then traded) for the
trading day immediately preceding the Conversion Date.

          Payee may elect to  convert  by  delivering  to Maker,  by  facsimile,
telecopier  or other  expedient  means of  transmission,  a notice of conversion
stating (i) the principal amount and/or accrued  interest to be converted,  (ii)
the number of shares of Preferred Stock or Common Stock to be issued as a result
of such conversion; and (iii) the person(s) in whose name the Preferred Stock or
Common Stock is to be issued. The conversion of any portion of this Note and the
resulting  issuance of Preferred  Stock or Common Stock shall be effective  upon
the date that Maker receives the corresponding  notice of conversion,  and Maker
shall deliver to Payee one or more certificates  evidencing such shares no later
than five days following such effective  date.  Upon a conversion of all amounts
due hereunder,  Payee shall deliver the original Note  (including all Allonges),
marked  "PAID," to Maker no later than five days following the delivery to Maker
of the conversion  notice. In the event of a conversion of less than all amounts
due hereunder,  (A) no principal amount under the Note shall be deemed converted
unless and until all accrued  interest under the Note shall be first  converted;
and (B) the portion of the amounts due hereunder that are so converted  shall be
deemed repaid. The parties shall mark on the grid attached to the Fourth Allonge
to Secured  Promissory Note dated May 10, 1999 the facts related to such partial
conversion  and shall  confirm the accuracy of the entry by signing next to each
such entry.

     4.   COLLATERAL SECURITY.

          The grant by Maker to Payee of a first  priority  lien on and security
interest  in all of  Maker's  Accounts,  Equipment,  Inventory,  chattel  paper,
documents and instruments, general intangibles, and all other goods and property
of the Maker pursuant to the Security Agreement between Maker and Payee dated as
of January 26, 1999, as amended, (the "SECURITY AGREEMENT"), shall also serve as
collateral for the indebtedness, fees, costs and other amounts evidenced by this
Revolving Credit Note.

one percent  (0.5%) of the  unborrowed  balance of the  Maximum  Loan Amount per
annum, payable on the 5th day of each month. Such unused commitment fee shall be
calculated  on the  basis of a 360 day year but  shall be  payable  only for the
number of days actually elapsed.

     6.   EVENTS OF DEFAULT.

          The occurrence of any of the following events or  circumstances  shall

grace  thereafter) all or any principal or interest or other payment  hereunder;

bearing debt for borrowed money existing on the date hereof; or

its debts as they mature, or (ii) making of a general assignment for the benefit

other holder hereof shall, in addition to any and all other available rights and
remedies,  have the right,  at its option  (except for an Event of Default under

other such right or remedy contained herein and/or now or hereafter  existing at
law or in equity or otherwise.

          No course of dealing  between the Maker and the Payee,  or any failure
or delay on the part of the Payee in exercising  any rights or remedies,  or any
single or partial exercise of any rights or remedies,  shall operate as a waiver
or preclude the exercise of any other rights or remedies available to the Payee.

     12.  GOVERNING LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL.
