Gentlemen/Madam:


Pursuant to Rules 477 and 478 promulgated pursuant to the Securities Act of
1933, as amended, Airborne, Inc., Airborne Express, Inc., ABX Air, Inc., Sky
Courier, Inc., Wilmington Air Park LLC, Airborne FTZ, Inc., Aviation Fuel,
Inc. and Sound Suppression, Inc. (collectively, the "Registrants")
respectfully request the withdrawal of the filing dated November 10, 2003 made
under Form S-3/A, as Post-Effective Amendment No. 4 to the Registrants'
Registration Statement on Form S-3 (Registration Statement No. 333-88102).
After discussions with the Staff, it is our understanding that the "Flag"
which was used for Edgar identification purposes incorrectly identified the
above referenced Post-Effective Amendment No. 4 as a pre-effective amendment
(S-3/A), rather than a post-effective amendment (POSAM). As discussed with the
Staff, immediately following the filing of this Form AW, the Registrants will
file Post-Effective Amendment No. 4 to the Registration Statement on Form S-3
(File No. 333-88102) with the proper Edgar "Flag" identifying it as a
post-effective amendment. The Registrants confirm that no securities have been
sold in connection with Post Effective Amendment No. 4.


                                 Sincerely,

                                 AIRBORNE, INC.
