I'm not a high-houred 737 pilot, so I ask questions and learn. And my questions here have not been answered, just hastily read, probably not understood and then ridiculed by some here.
I am a 4000 hour 737 captain and i will admit that I don't know for sure if I understand exactly how this happened. I think that they may be getting flare and retard mixed up in that the A/T went into Retard rather than thinking that it is in an autoland flare. There is no way to get into the flare mode in a single channel approach (as far as my system knowledge goes) and a RETARD mode will be followed by ARM....
