A few years ago I went to Dublin to get revalidated on the B737. The TRE tried to tell me that at the flare, both hands would be required on the yoke. What for? says I. Because it is so heavy and you will have more precise control says he. Bull**** says I , and who will select reverse? The FO does that says he. Not on my watch says I, unless he did the landing.
It was an interesting insight into some fckud up training inspired presumably from watching too many B grade WW II movies.
But I did note that wearing white gloves seemed to make it work for him.
