Must have been along the coast and in the 1990s?
The original Flight West very successfully operated B200 King Airs to 17 air ports in Western Queensland, from bases in Brisbane and Townsville.
The EMB120 Brasilia was the perfect upgrade from the King Airs on the Western routes.
The only other aircraft were three air conditioned Beech 58 Barons based at Roma and Longreach for the Flying Surgeon/Flying Gyno.
It was a great operation with wonderful, professional, dedicated people in those early days.
