It was noted that, in addition to runway 12/30, runway 8R/26L at MIA had similar threshold lights that did not meet the current standards.
All the more reason BA should have generated a briefing bulletin for pilots, as MIA was, and still is, a regular destination for the airline.
I worked for two small(er) airlines that had the capacity to generate these briefing bulletins...and one of these is now the largest in SE Asia.
So, the question then remains...just why was BA not up to snuff, in this department?
