[QUOTE]Originally posted by George Harris: [QB] Before everyone gets all warm and fuzzy about PTC, remember anything invented by man has the possibility of error. Note Smitty's "it is always a chain of errors that leads up to a crash." All PTC does is put one more link in the chain, which also gives it one more place to break. Increased complexity does not necessarily lead to increased safety. The NTSB and before it the ICC are notorious for recommending expensive mechanical solutions to solve all human error accident, and also while making these recommendations blithely ignoring both examples of their failure and any thought of cost-benefit ratios. I hear some dolt sounding shocked that they were depending upon a "red light" to tell the engineer what to do. What do you think we all do when driving down a city street? [/QB][/QUOTE]
