Zube,
I beg to differ with you. Ansett opertated twice daily F27's from ASP to AYQ, with 1 return often being cancelled due to lack of numbers.
I know because I cabin crewed plenty of them as well as quite a few "track trips" to DRW via Tennant creek and Katherine. Have the slides tucked away somewhere to prove it. We often operated them in the old "egg and lettuce sandwich" Airlines of NT livery F27.
I started in 1980. Can't tell you when they ceased, but they were bloody good 5 and 6 days trips.
