F 18fighter

I saw a discussion the fighter f 18 that bothers me. It seems the plane has brake problems and according to the article - in order to stop the plane - the pilot has to go through a lengthy procedure. If this trouble has been known - why can not it be fixed. Supposedly quite a few planes and pilots have been lost. Is it politics or what is it that troubles do not get fixed until pilots have been lost and enough blood has been spilled. Why does the Government go though things like this? It seemed like in the past F 16 went through the same things only I think that time it was the Wiring in the wrong location or what ever was wrong and many planes and pilots was lost? Does it really cost too much to fix the planes? Eventually the money has to be spent to fix the troubles. Either that the system in the Military does not work and the management covers up the problems. I do not know but maybe they need a different type liason people to run around with a cup of coffee in the hand but with some common senses to find the right people whether they are low on the scale but the bosses in so many cases do not know the answers and are paid too much - or are not willing to let the lower eschlon do the thinking and the work.
