Two-seat general-aviation airplanes have had a checkered career at best. For every Cessna 150/152 or Citabria that’s had a model run of 30 years, there have been a half-dozen other types that only lasted for three or five.
The short-termers may have been no less viable as trainers or fun two-seaters, but they nevertheless failed to survive. Fact is, two-seaters are generally a tough sell, even if statistics prove that most of us rarely use all four seats in our quartet airplanes. (It’s been 12 years since I’ve filled all the seats in my Mooney.)
