This one brings back memories. I was in college at the time, Northrop
Institute of Technology, in Inglewood, CA. We had a class field trip to the
Wing Aircraft Co., in nearby Torrance, and we saw two or three in the
building. One was being converted to a test aircraft for a COIN venture.
(COunter INsurgency). I believe it was going to be a display at Paris. They
had already lost one in Florida, I think, during spin testing. They also
gave the argument of why it was only a 2-seater.They said, studies were made
that most 4+ place aircraft were only flown with 2 people, so why waste
metal on a biggere aircraft? I think that philosophy killed them.

That design philosophy was part of the problem. The rest was that they
used an etch on the aluminum as part of the bonding process.
Unfortunately, they did not sufficiently passivate the etch, so it
continued to etch the aluminum after bonding. The result was a lot of
airframes suitable only as planters.
