I have read a lot about Cape Air.  They are a small operator in the New England area flying a fleet of (mainly) Cessna 402s.  The reason I know this is that they have been heavily involved in the development of a new piston twin with Tecnam which they intend to use to replace their fleet.  The first examples have started to show up but, for now, the 402 is still their workhorse.  While I was sitting at a gate at Logan waiting for a flight home, we were right across from their ramp so I was able to watch the comings and goings of their planes.  Seeing them mixing in with the big airliners was pretty impressive.
