I find that an astonishing statement and hard to believe. I recall the first simulator I flew was during a Boeing 737-200 type rating course in New Zealand 47 years ago. By todays standards it wasn't sophisticated. When on completion of the simulator training I then underwent dual instruction on the real 737, everything came quite naturally to me starting from the first taxiing. In fact the only difference I recall between the simulator and the real thing, was the aircraft I flew had extremely difficult reverse thrust lever movement which was most distracting on the landing run. It was after I flew other 737's where reverse thrust was easily attained that I discovered the first 737 was poorly maintained.
