Do you think that the Light Sport category has any potential?
The restrictions in allowable gross weight, number of seats, operations, power and speed mean that these are traveling airplanes only for the most patient and determined, but they are relatively inexpensive to buy and to own and they are good for the type of low and slow summertime flying most GA pilots did back in the day.
While they may not enjoy FAA type certificates, they are at least available new at a reasonable price.
There are also amatuer built experimental category aircraft, with plenty of traveling airplanes to choose from, but the high performance ones aren't cheap or quick to build, and having someone ghost-build one for you is neither cheap nor legal.
A former state governor, a progressive Republican named Jim Rhodes, made sure that every county in Ohio got an airport and a community college.
The community colleges are mostly thriving.
Many of these airports are ghost towns and you wonder how an FBO can survive on them.
I think that Cujet is right in that fuel prices are killing GA, with many piston airplanes seeing very few hours of flying each year.
I don't know how anyone could afford regular use of a piston twin today.
I'm not sure where the solution lies, since avgas, whether 100LL or some new unleaded fuel is a boutique product produced in limited batches to meet limited demand, with higher prices further reducing demand resulting in lower production and even higher prices.
