CURIOSITY FOR THE CURIOUS: Visitors - of which there were many - going aboard the Do.X at Calshot on its way to South America.

The photograph shows the excellent internal arrangements which have been made for the passengers' comfort, and also the tasteful interior decoration. The engines are accessible during flight, and by means of a small alley-way along the wing the mechanics are able to go from engine to engine, and should any engine stop and require attention this can readily be undertaken.
