JSF and all those other Fan's
We could go endlessly debating the merits or failures of the F35 program
but maybe it would be better to explain why so many are so sceptical about this whole F35 program.
They pretty much have done every trick in the book to let this thing go ahead and keep it alive, starting from over-promising and underpricing the whole project, while basing too many of its systems and technologies on underdeveloped or even non-existing technology, setting future goals that cannot be met (wait until something like an MLU needs to be done) and promising a 1 fighter for all tasks from the get-go, a failed policy on almost all defense programs in the past and present.
A good read is this 2008 piece on why the weapons acquisition seems to be no longer working as it should.
Extrapolating for the F35, it is sinning on most, if not all of the issues explained and that is why I think that the F35 is just not a good idea for most of our military.

Another thing you might want to consider is the fact that so many high placed military men and people deeply involved in the program have been openly critical about the whole JSF debacle.
If you have any experience operating in a military environment you would know that it takes a lot of wrongdoing before people speak out openly and critically about projects like these.
Loyalty towards the military and everything related to it is usually much higher than in the normal civil world, it takes a lot for so many people to be so openly critical about the F35.
