Time? When do you think that you will get F-35 IOC? And at what cost, since anything before 2015 delivery is LRIP and costs over $100m a pop, and the 2015 price won't be fixed until 2013?
Legs?
Might have been the case once but no longer - there is now relatively little difference between the F-35 and Typhoon or Rafale, just that the F-35 carries all fuel internally.
