Willard Whyte,
Just hope the Chinese are not going through the same problems with their version the J-31. Having written that, since they stole all the files for JSF I suspect hey may well be aware of the issues and have worked around them.
I bet the Chinese get their aircraft in service before JSF appears.
That would be an embarrassment. Perhaps that's why the Americans won't give up on the project? I reckon we will be on Double Z plural alpha before we get a working one
