Here you can see the super
secret
Norden Bomb Site in the bottom of the picture.
Pilot, Co-Pilot and Bombardiers
Station.
In an aircraft this large the crew
accommodations were very cramped.
The forward bomb bay can be seen
through the small window in a pressure door in the bottom centre of
the bulkhead under the tunnel entrance. The tunnel is barely
visible above the centre of the main spar at the top of this photo.
The main wing spar separates the forward and after bomb bays.
