Not known why this was in Adelaide, perhaps for evaluation for South Australian service. Another pic taken at the same time shows a few orange vested people by the plane.

This CRJ was delivered originally to Kendell Airlines in January 2000 as VH-KJN. From April 2003 it was operated as a United Express affiliate by Mesa Airlines. The frame was then destined for Go!, a HNL based regional brand Mesa Airlines that operated inter-island services within Hawaii, however, they ceased operations a week after this shot was taken. Instead, the plane was ferried to Stuttgart (SGT), AR for scrappage.
