Too bad they got the history wrong. The Germans had it first during
WW2 with Baumgartl's Heliofly III:

The Heliofly III, as actually built, wasn't a backpack helicopter, as
evidenced by the photograph at the bottom of the same page you cite.

The Heliofly I was a backpack autogyro, which is a similar (though very
limited) idea.

Note also that designers as far back as the 1920s had suggested backpack
or personally-worn autogyros or powered flight rigs.

Once again, a German scientist in the 1935-1945 era who drew something
he couldn't build...
