What is so remarkable about a decision to operate an aircraft on RPT services that:
* Provides optimum passenger comfort in a low capacity aircraft.
* Provides the lowest seat/mile cost of any aircraft in it's class.
* Has a demonstrated safety and reliability record which exceeds that of piston twin aircraft.
* Is very rugged and able to operate into unsealed airstrips as short as 400 meters.
* Is modern technology with minimum maintenance burden.
* Has a greater payload over a 250 nm sector than a DHC6-300 Twin Otter or Embraer EMB110 Bandeirante.
* Has a range in excess of 1,000 nm.
* Is simple to operate, no vices and a delight to fly.
* Powered by the greatest small turbine to ever turn and burn.
I could go on, and on, and on - but I think that will give you enough to argue over for now.
Caravans, flying cash registers -
