They were just a little bit more ambitious than the Europeans so you might want to cut them a little slack? Or not - up to you.
Far too ambitious - as a taxpayer I do not want to cut any slack -
The whole F35 program(me) is bizarre,as we have said many times - the non stovl versions design is compromised by the stovl version design.LM have bitten off a whole lot more than they can chew with the F35B and from a technical/maintenance point of view it will be a bit of a nightmare !
