To the uploader: Please add a detailed non-free use rationale for each article the image is used in, which must also declare compliance with the other parts of the non-free content criteria, as well as the source of the work and copyright information. For example non-free use rationales, see Wikipedia:Use rationale examples. This tag should only be used for aircraft images. Template:Non-free use rationale may be helpful for stating the rationale. To patrollers and administrators: If this image has an appropriate rationale please append |image has rationale=yes as a parameter to the license template.

Additional rationale

The aircraft depicted in the image was never produced and/or no intact examples of this aircraft remain in existence today, therefore creation of an equivalent free image is impossible.
