The Grade monoplane of 1913. Of this curious German creation, Jane’s said:

“A curious little monoplane built purely for aerobatics, and designed to alight upside down, as a circus trick”.

But what I want to know is why Herr Grade bothered with the work that went into designing an aeroplane that could land inverted. Many subsequent aeroplanes managed to achieve that without having such a design feature built in!

Yes, but how many could take off that way?

Actually, did Grade ever actually ever land this machine that way? Or did he have second thoughts about what might happen to his head if the rather flimsy-looking under(over?)carriage failed?

Anyhow, time for the next one.

Gives new meaning to the term “sailplane”. But see http://www.ohtm.org/demenjoz.html

Just to keep the thread alive.

For your amusement.

Yes. Take over.

A waterplane for a change.

Yes. Your turn.
