    …A blog by Trisha Volpe, at Minnesota Public Radio. She details progress being made at the airports in Duluth and Superior, including: (1) recovery of the large hangar abandoned when Northwest went bankrupt (now an AAR commercial maintenance facility); (2) Cirrus, which saw very lean years during the down economy but is now ramping up production with a new single-engine personal jet; and (3) Alan Klapmeier’s Kestrel turboprop project, aimed at corporate flyers, and being developed at Superior Airport (NOTE: Klepmeier founded Cirrus but left the manufacturer shortly after it was bought up by a Chinese company in 2011).
