He's just another bloke with an opinion!...not necessarily the correct one!
You miss the point completely. Mac Job is a first class aviation journalist. His expertese lies in his ability to plough through pages and pages of an accident report and by picking out the salient points turn the report into an eminently readable account of the accident. The "opinions" you complain about are nothing more than views of accident investigators put into intelligent and concise English by Mac. In his Air Disaster series he chose the subject matter after consulting with various experienced airline pilots. He has never pretended to be an "expert" but rather a fine journalist and former pilot with a wonderful flair for writing with dignity.
And by the way. No mention has ever been made of the professional "mouths for hire" brought from Europe that were presented by the defendents as so called expert witnesses at the court case. I sat next to them in the court room.
And as to the knowledge of the position of the circuit breakers in the 737 and other technical matters pertaining to the operation of MI 185, you might be interested to know that Mac was an observer present in the 737 simulator when various crash scenarios were tested. Forget the uncommanded runaway rudder theory too. It was dead easy to recover from that at cruise altitude in the simulator even with a 10 second delay before countering its effect. Been there-done that.
