It appears that something was changed with the way bomber control is viewed now in F3 external view mode.
Previously when in this mode when you used your joystick to move the bombers, the terrain remained level and you saw only the planes bank / climb / dive. Now in F3 mode not only does the planes move, but the entire terrain moves along with it.
Was this intended by design? Makes for some additional nausea when playing the game now...would prefer to have it put back.
Cheers,
