You could certainly start up and taxi a Halifax on your own around Aldergrove airfield. My father would stick me in the nose during brake-bedding runs. Presumably there was little else to do when airborne than raising the flap and undercarriage; Varsitys would be flown solo without any trouble.
My rides stopped when there was a total brake failure on the northerly runway and he had to open up the starboard outer and ground loop it amongst the spectacles on the northwest corner of the airfield.
