Why on earth has this to do anything with "taking part on this top-gun competition" ?
Following this logic, none of the JH-7 or J-7 units are operational, since they don't take part on such an exercise.
How many J-10 units are then "operational" ??
Only that they are too new and did not take part in these public well known exercises does not mean they are not operational !
I really would love to argue with You or discuss ... but all You have is Your hate against this type of engine, Your belief in Your opinion, but You have no proof ! For none of Your strange points ...
