- The X-112 was Alexander Lippisch's first reverse-delta 'Aerofoil Boat', built at Collins Radio and described in Lippisch's US patent 3,190,582.
- Height is not published, so the file models only a 7.62 × 4.27 m plan-view envelope (data from Jane's All the World's Aircraft 1964–65 via Wikipedia).
- The patent text was not readable in this research pass, so no patent geometry is recorded. Marked secondary.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
