20 plus years of declineAfter over 20 years of decline people are still hoping for this stock to take off lol.The idea of investing in what they do isn't bad .It's just bad to be invested in at least so far.It may catch on and take off but that doesn't mean it won't do diddly for another 20 years where you would have been better off investing in just about anything else lol.Maybe use the technology that finds planes in a side product like pet location .People are more interested in where their dog is than where their plane is
