Blohm & Voss Ha 139


from wikipedia

The Blohm & Voss Ha 139 was a German all-metal inverted gull wing floatplane. With its four engines it was at the time one of the largest float-equipped seaplanes that had been built. The inboard engines were mounted at the joint between the inboard anhedral and outboard dihedral wing sections, above the pylon-mounted floats.

Further development of the Ha 139 led to the land based version Blohm & Voss BV 142 which had its first flight in October 1938.
