It is not just some airlines that have banned the dive and drive but STATE (as in countries) authorities as well!
The operative word being
some.
Not where we fly, they haven't.

Many say the the CDA is better, and yet....we are discussing an accident where the aircraft was so fitted with all the latest and greatest kit to do the deed, and the pilots (being factory trained) surely must have been trained accordingly...but the airplane crashed anyway.
Nope, simply not convincing.
