Gliding
At 600', with less than 60 seconds to touchdown, no power and in the landing configuration, the ONLY action that won't make the situation worse is to hang on to CLmax (the edge of stick-shake) and if landing is inevitable, make the best touch-down you can. This is the standard procedure for extreme down-draft or terrain proximity recovery i.e. max lift and don't change the config. This action appears to be exactly what occured in the case of BA038.
To suggest that one might train crews for an event that has happened once in the history of jet aviation and is, as yet, unexplained, is to fail to understand training priorities.
Why not wait for the findings of the Enquiry?
