A very minor point - the D.H.86 only required one pilot, the D.H.86A required two. As the in-game model requires two pilots, I would assume it should be a D.H. 86A, although I believe the photo is of an original (one-pilot) D.H.86
On a related point, I have for a while thought the game should re-term pilots 'flightcrew', as across several game worlds there are types requiring as many as 5 pilots, who in reality are a mix of pilots, flight engineers, radio operators and other flightdeck personel.
Interestingly, if we make a habit of including these extra flightdeck personel, many of the older aircraft in this world (including my above D.H.86) should have an extra 'pliot', as most aircraft of the time had a wireless operator. In which case, the D.H.86 would have two 'pilots' (making the game correct at the moment, but missuing 'pilot' as detailled above), and a D.H.86A would have three 'pilots'.
Generally the whole area is a bit ambigous - do all models in game include all flightdeck personel as 'pilots'? If so, they should be renamed 'flightcrew', and all types updated with the correct numbers.
