Comment: Currently, all but one of your sources are user-generated content meaning they aren't considered reliable, at least for the purposes of determining notability. I'm also unable to access the reference to ABPic (even through archives), though it seems like it is similar to the reference to Airliners. Finally, I'm unfortunately unable to access the reference to Keimel, and I'm not seeing any databases that currently contain it. (This isn't a problem, to be clear.) However, I'm curious how in-depth the book talks about this plane (e.g., how many paragraphs/pages)—can you offer some insight there? Perryprog (talk) 19:37, 18 September 2025 (UTC)

Löhr's design was based on the work of Alexander Lippisch and aimed to be an aircraft which had a large wing area, take up minimal space in a hangar, and have good slow-speed flight characteristics.[1][2]
A scale model produced in 1970 verified the qualities of Löhr's design, and led to the construction of a full-size aircraft. It was constructed from composites and aluminium. The centre section of the aircraft comprised a fully faired fuselage, with two occupants sitting side-by-side, a nose-mounted engine driving a tractor propeller, a central fin and rudder, and was supported by a fixed tricycle undercarriage. Control was by full-span elevons and rudder. The outer portions of the delta wing, trapezoidal in shape, could fold up to facilitate storage.[1][2]
The Delta was not inspected during construction, and did not receive official certification of airworthiness.[3] In 1990, taxiing tests were conducted at Zell am See, without any flights being made.[4] The aircraft was later placed on display at the Museum of Vehicles, Technology, and Aviation at Lauffen near Bad Ischl.[1][2]
