Wratten stated MALM Forbes wasn't carrying out his Nav duties. Wg Cdr Pulford thought he was. There is a little spat going on between the current CAS and a more junior retired officer. (A situation which I suspect brings a smile to one, and makes the other kick his cat). If MoD ever answer the question, let us know as I agree it is important.
As you know, a few years ago MoD would never answer such a question. Nowadays they might. After all, on 28.2.12 they admitted that the Mk2 only had a ground training and familiarisation clearance on the day of the crash; due to be renewed within 2 weeks.
