Genghis,
No luck yet - you have a point, I must admit. Yet I am adamant, at Carlstrom Field, Arcadia FLA, (Sep/Nov '41), the Instructors always flew solo from the front, the "Aviation Cadets" (aka LACs) always from the back.
Mind you, the fact that the ASIs were only in the front may have had something to do with it !
Yet, ('instructing') or solo, I always flew a Tiger from the front. Why should they be different ?
Danny.
