If you fly MD-11's, though, I think in general that it is a good idea to be proficient in bounce recovery. In general, that is a good idea.
Fully concur with the Japanese authorities' methods. Also fully agree with you re bounce recovery, and that means bounce recovery for all types, not just one. It's just a very good idea as you say and should be standard kit.

If I may, I think you're probably going to have to wait a bit for the answer to your question as the Japanese authorities have not yet released their report and have asked that comments not be made in public yet, but have discussed specifics with the operator. I think that is plenty and respects both the investigative and safety processes.
