Let's not forget one of the principles of our industry. The general concept is to share information so that the mistakes of others are published to prevent reoccurrence. One would have hoped that previous events would have become known to all operators into SFO and warnings issued about the risk. To have multiple similar errors over such a short time frame is very disappointing. As well as commenting on each individual event it would be prudent to ask why they continued to reoccur. There seems to be a weakness somewhere that needs strengthening. If that weakness is in SFO's local procedures, that is one issue to address; however my initial comments are more focused on why crews are repeating this mis-identification.when they should be aware and extra vigilant.
