The Rumpler Biplane.
This biplane with the Aviatik is remarkable for the amount of space provided for pilot and observer. The fuselage is protected in front with aluminium. The upper plane is not made to join in the centre, as in most German machines; instead, there is a short immovable central plane, which is permanently attached to the fuselage by four tubes; to the ends of this central plane, on either side, the other planes are fixed.
