I’m not sure about it ‘landing backwards’ but I have seen one put down with virtually no forward landing roll so, theoretically and given full flaps and an appropriate head wind, presumably it could make a controlled vertical descent and landing. But on this theory I’ll defer to those who have flown a Storch/Criquet.

Quite, I have seen some of wartime footage of them landing in strong headwinds and they appear to stop in the length of a cricket pitch which given their slow flying ability was probably a long landing. I personally would not want to be trying to land the aircraft if I found myself drifting backwards.
