I see the F-35s fly nearly everyday. My opinion, budgeting issues aside, they represent a huge shift away from what we traditionally view as air superiority or dominance. Much like AWACS was a huge step forward, the F-35's capabilities takes that even further. New tactics/doctrine mixed with new technology......remains to be seen how it will play out in a real world situation. One we haven't seen yet...........that we know of anyways. Also, I keeping reading around the 'webs all the naysayers saying how they've been grounded forever and they're flying turds, yada yada, I just have to laugh. They are quite operational, and have been for a long time. And, they are impressive to watch. Along with the Raptors, they will leave you questioning all your understanding of the laws of physics and flight.
