Secret Projects book on STOVL/VTOL designs?

[Hanse]

Has there ever been a Secret Projects book on STOVL/VTOL designs? I know there are some of those designs sprinkled about the various Secret Projects books but wondered if there had ever been a volume with them collected together.

There is this one. It's not part of the "Secret Projects" series per se but does provide quite a good coverage.

I'm guessing that this is the English-language translation of the same book:
