The picture is far wider than just businesses.....
Of course the GA industry is falling apart. We still fly aeroplanes from the 1970's and earlier. The most common engines have barley changed from the 1950's! If that is not indicative of the GA industry as a whole I'm am buggerd if I know what is. Yes, GA needs to adapt to the changes, but it is my thinking that the WHOLE industry needs a shift - and I think that will actually happen. For some, that wont happen soon enough, and when it does, it will be to rapid for others. Fun times inbound.
