Many 320 trainers will follow this resigning training captain soon.
They are waiting for few weeks because of a promise to move their TREs soon to the next fleet.
Also Many 330 trainers are waiting for the removal of IM from his post, since the latest news indicates that he has failed his last medical check (heart problem).
I personally wish him to get well soon with a speedy recovery, in spite of the disagreement with him technically, but there is nothing personal.
