Analysis of Results for the Three Months Ended
September 30, 2000 and 2001:


The terrorist activities of September 11, 2001 had a negative impact on Big Sky
Transportation's ("Big Sky") operations. Management estimates that the federal
ground stop order, which effectively suspended operations for approximately 4
days, along with decreased passenger demand resulted in approximately $400,000
in lost revenue during the period September 11-30, 2001. Big Sky received
$253,253 in initial federal aid from the Air Transportation System Safety and
Stabilization Act (the "Act") that partially offset these lost revenues. Big Sky
expects to receive another $253,000 in federal aid under the Act by early 2002.
While the long-term effects of the terrorist activities are not readily
determinable, management believes that decreased passenger demand will continue
into the second fiscal quarter of 2002, although not to the extent experienced
in September 2001. The Act also provided an authorization for Essential Air
Service ("EAS") subsidy funding at $120 million for the period October 1, 2001
to September 30, 2002, that is substantially greater than the $50 million EAS
subsidy level authorized prior to the events of September 11, 2001. The ultimate
amount of funding is subject to congressional appropriation which has not yet
been established. Big Sky would be eligible for any additional subsidy funding
that may occur to offset the decreased passenger demand. Management believes
that liability insurance premiums and security expenses will increase during the
remainder of the fiscal year as expenses and losses related to terrorist
activities are spread among passenger air carriers. The Act contains provisions
that may provide federal aid to partially offset the increased insurance
premiums and to fund the increased security costs.

Big Sky's operating results, excluding the September 11, 2001 terrorist
activities, reflect year-over-year increases in operating expenses, most notably
payroll, aircraft ownership and maintenance expense, that have exceeded
increases in revenue. In late July 2001, Big Sky began service from Moses Lake,
WA to Seattle and Spokane under a new EAS contract. This new service partially
accounts for the increases in operating expenses referred to above. Preliminary
results, from inception of service to September 11, 2001, met management's
expectations.

The combined impact of the September 11, 2001 terrorist activities, new Moses
Lake service and a general slowdown in the U.S. economy resulted in an operating
loss of $401,494 for the three months ended September 30, 2001 compared with
operating income of $144,541 for the same period in the prior year. It is
important to note that under accounting rules set forth by the Financial
Accounting Standards Board's Emerging Issues Task Force, the $253,253 in federal
assistance under the Act is classified as non-operating income.

                            ==========     ==========     =========


The modest 1% increase in passenger revenues reflects new Moses Lake service and
growth in existing markets offset by the September 11, 2001 events described
above. The increase in public service revenues is due to an increase in subsidy
rates, effective December 1, 2000, for Big Sky's northern EAS route system, new
Moses Lake service, and a higher year-over-year flight completion percentage.
The increase in other revenues is due primarily to funds received under an
agreement with Lea County, New Mexico whereby the county will provide an
operating subsidy (not to exceed $35,000 per month) based on a number of factors
including flight completion, passenger revenue and allocable expenses. Included
in other revenue is approximately $100,000 related to this agreement.

                          ==========     ==========     ==========


The increase in flying operations expense is attributable to increased pilot
payroll, fuel and aircraft ownership (e.g., lease, property taxes, insurance)
expenses. Pilot payroll and fuel expense increases are primarily attributable to
and consistent with additional flight hours associated with new Moses Lake
services. Aircraft ownership expenses reflect the



                                       8


addition of two leased aircraft in the second half of fiscal 2001. Fuel prices
decreased slightly on a year-over-year basis.

The increase in maintenance expense is due to higher payroll expenses, airframe
and avionics repairs, maintenance material consumption and engine reserves. The
increase in payroll expense is due partially to the opening of a new maintenance
facility in Ponca City, OK in October 2000. This facility replaces a maintenance
facility located in the southern region that was closed in April 2000. Wing spar
inspection and repair on two aircraft contributed approximately $86,000 in
incremental airframe expense. The increases in avionics, maintenance materials
and engine reserves reflect the addition of two leased aircraft and higher
year-over-year flight hours.

The increase in traffic servicing expense is due in part to additional traffic
associated with new Moses Lake service and additional service to Denver. Also
contributing to the rise in traffic servicing was an increase in Big Sky's
passenger liability insurance.

The increases in marketing and general and administrative expense are consistent
with the above increases in passenger traffic.

The increase in depreciation is attributable to the purchase of an additional
spare engine, leasehold improvements associated with leased aircraft and gate
facilities in Dallas and the purchase of customer reservation software.

Period-ending September 30, 2001        $1,529,337                 $317,567

Cash provided by operations for the three months ended September 30, 2001 was
$541,771. Cash used in investing and financing activities was $53,443 and
$488,328, respectively during the period.

Big Sky has established a line of credit through First Interstate Bank and Trust
Co. of Billings for an amount of up to $1,500,000. Big Sky uses the line to
supplement timing differences in cash flows. The maximum amount drawn on the
line of credit during the quarter was $1,500,000 compared to a low of $423,096.
The losses over the past two years have required Big Sky to increase the use of
the line of credit. Management is evaluating options to increase Big Sky's
capitalization to reduce its reliance on the line of credit.
