They have continued selling that particular model non stop quite succesfully. If you ask me, this is their lowest risk airframe. If I have to make parts for it, I can. If the gear doesn't work, I have a nice set of matrix that will drop right in. So really nothing to it......
Ive owned pbly 12 F-16s, to me they are like trainer 60s, including FEJ. Nothing to them. Can't speak for any others except their F-35 which I also have and so far so good.
