Here is a photo of a "cloud-UFO" shaped configuration of UFO vehicles in monograph [1/5] called "herringbone". Only that in the above photo this configuration is hovering in a "hanging" position, and not in a "standing" position in which our forest eateries (Christmas trees) are typically oriented. Descriptions of the herringbone configuration are contained in subsection #G3.5. from volume 3 of my newest Monograph [1/5]. In turn drawings of the principle on which such a configuration is formed are presented in Img.050 (G8-2) and Img.130 (P11) from that newest monograph [1/5].
