EXHIBIT 10.21(a)

Amendment Number One
to Acquisition Agreement


	This Amendment Number One to Acquisition Agreement by and among 
Jetstream Aircraft, Inc., a Delaware corporation ("JAI"), JSX Capital 
Corporation, a Delaware corporation ("JSX"), and Atlantic Coast Airlines, a 
California corporation ("ACA") is dated as of June 19, 1996.

	Whereas, the parties have entered into an Acquisition Agreement for 
Jetstream 41 Aircraft (the "Acquisition Agreement") dated as of December 30, 
1994, which Acquisition Agreement provides for the lease to ACA of twenty 
Jetstream 41 Aircraft (as defined in the Acquisition Agreement) on terms and 
conditions contained therein; and

	Whereas, eleven of the Jetstream 41 Aircraft have been delivered and 
leased to ACA pursuant to the Acquisition Agreement, and nine of the Jetstream 
Aircraft (the "Undelivered Aircraft") have not yet been delivered or leased to 
ACA, and

	Whereas, Section 9.1.8 of the Acquisition Agreement contains certain 
conditions precedent to the delivery of the Undelivered Aircraft, and the 
parties desire to clarify the effect of said conditions precedent and to amend 
the obligations of the parties with respect to said Undelivered Aircraft;

	Now therefore, for good and valuable consideration, the receipt and 
sufficiency of which is hereby acknowledged, the parties hereto acknowledge 
and agree as follows:

1. Section 9.1.8 of the Acquisition Agreement is hereby deleted.
 
2. ACA's obligation to accept delivery of, and JAI's obligation to deliver, 
the Undelivered Aircraft is hereby canceled.  The parties shall have no 
further obligations with respect to the delivery of Undelivered Aircraft 
unless ACA elects to exercise the option as described below.
 
3. ACA shall have an option to accept delivery of any of the Undelivered 
Aircraft on the same terms and conditions as contained in the 
Acquisition Agreement subject to the conditions precedent in the 
Acquisition Agreement and further subject to the following:
 
a) This option shall be exercised by ACA's providing written notice 
to Jetstream of its intention to accept delivery of any of the 
Undelivered Aircraft.
 
b) The option may be exercised in whole or in part, and may be 
elected incrementally until expiration.
 
c) The delivery date of any Undelivered Aircraft shall be specified 
in the notice but shall be at least six months after the delivery 
of said notice, and with all deliveries to be completed on or 
before June 30, 1997, both unless otherwise agreed by the parties. 
 Jetstream's obligation to meet a delivery date specified in a 
notice shall be subject to availability, but in that event 
delivery shall be completed as soon thereafter as Jetstream has 
available delivery positions as of the date it receives notice.
 
d) This option will expire for any Undelivered Aircraft for which a 
notice of exercise is not delivered on or before December 31, 
1996.
