Why does a tricky airport like San Francisco not have all the safety system working?
Sorry not a pilot, but after the last crash one think we would learn a important lesson.
What exactly was not working? I have no clue what you are talking about.
SFO does visual whenever possible to increase throughput. This is similar in spirit to what is done at Penn Station approach from the east where routinely trains proceed on restricting speed visually crawling upto the tail of the train ahead.
Are you suggesting that they should stop doing so? That will reduce the throughput capacity of SFO by more than 50%, and is not going to happen.
They still have PAPI to guide them to the landing spot. When someone loses situational awareness, all bets are off, unfortunately.
It is possible that if they had the Rabbit on it would have reduced the possibility of this particular mistake, and that might indeed be a recommendation that comes out of this. Saxman and I had an interesting discussion about this at the AU Gathering.
BTW, in a preliminary NTSB review, a representative of the SFO ATC said that the big red "X" was lighted at the end of the out of service runway 28L at the time of the incident.
Incidentally also, because of the displaced threshold of 28R, most fortuitously, the landing craft overflew the first two planes awaiting takeoff on Taxiway Charlie, instead of crashing into the first one in line. That gave ATC the time to react and command the go around just in time- some say within five seconds of disaster involving the landing plane and the third and fourth plane in queue on Charlie.
