as a defence of the Faithful Annie (Anson), the view from its cockpit was fairly good even if it was a low wing a/c. One of the reason why the only sqn that flew operational patrols with Botha, 608, wanted its old Ansons back was that even if Botha had shoulder wing, view from it was much worse than from Anson. Anson was also very easy to fly, so easy that it wasn't very good training a/c.
The training missions mentioned in a previous post - the WO would sometimes become the pilot of the Anson. Also, some pilots allowed the WO to take off and land the Anson. This ended when a seagull crashed thru the nose of the a/c and it crashed when taking off (no casualties).
