Not overly special but not something CNS would see every Monday, with a 2-class B717 operating what seems to be a charter rotation ex-BNE today as QF1950/1951. Due in 1150, out 1230. VH-YQS is the bird in question.
B-4011 CRJ-200LR PLAAF should be with you in the next 30 minutes or so, on her return flight to China after an extended period at Melbourne-Essendon. This is the last of their CRJ's to come this way for maintenance.
