There are many markets that will survice only with the use of turboprops. Which at any rate, have jet engines attatched ot those wings. They just turn props instead of fans. Mesaba is not going to be all jet - we are retiring saabs but have the last 340s off the assembly line and it has been said that we'll operate 45 saabs in the future. Cities like Thief River Falls, Bemidgi, Brainerd, St. Cloud in MN
, Pierre and Watertown in, SD
and all kinds of other small towns in that neck of the woods survive on air service. Should an RJ
not be able to profitable serve those towns - an all jet airline would have to suspend service there, thus leaving the city without a vital link for goods and other services.
Yes, there will be a need for turboprops in the future of American aviation.
