Unless the pilot does the walk around at Dep-10 mins or so, then they are likely to see all sorts of ground equipment attached and engineering still crawling over the aircraft. Half the time I do the walk arounds the engineers are topping up the oils. I believe BA is one of the few airlines where the same engineer can work on both engines...I know it has been brought to mgmt attention before . Who will take the fall? Some poor overworked line engineer being ordered and timed from aircraft to aircraft, or the designer of a time management system that allows this?
