Meet the Blohm und Voss BV 141.
Yes, it’s all there . No bits have fallen off or been forgotten. What’s more, twenty were built. More would have been, but the BMW 801 engine it used was in demand elsewhere.
You want to see one flying, don’t you? Of course you do.
Naturally, the late Eric Brown flew one because of course he did. He flew everything.
Blohm und Voss no longer make planes, even symmetrical ones, but they will get you afloat. Their former air division wound up in Airbus along with much of the German aerospace industry.
