Oh, and the Cri cri is the lightest human piloted jet to have flown,
the BD-5 is shorter and thus smaller by that measure. IIRC
the Juan Dart holds the record because it is a small as any
other BD-5 and lighter than the others by virtue of omitting
components needed for self-starting. The Guiness Book
people evidently do not require that it be flown in that
configuration to hold the record, which strikes me as peculiar.

Could the record be snatched away buy putting a couple of those mini
turbines on something like a Mitchell Wing?
