Man-machine interface and anomalies

[RR_NDB]

Do we know everything that occurred that night?

...that nothing have been missed, which is something I suppose.

Clearly there are unsolved questions. When working in so exciting issues we need to be open minded like we need when driving a machine that can always present surprises. An a/c is female, so surprises present challenges to us.

Probably the focus should be the "interface" which IMhO created "HF issues".
