Reconstruction of the 2016 Gerlingerstraße (Germany) formation | ||

1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | |

2. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up. | |

3. |
Construct two inscribed equilateral triangles of circle 1, one pointing up, one pointing down. | |

4. |
Construct a circle concentric to circle 1, passing through the mutual intersections of triangles 3. | |

5. |
Construct a circle centered at the lower angular point of hexagon 2, tangent to circle 4 at the lower side. | |

6. |
Copy circle 5 five times, to the other angular points of hexagon 2. | |

7. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 5 and its intersection (tangent point) with circle 4. | |

8. |
Copy circle 7 to the center of circle 1. | |

9. |
Construct a circle centered at the lower intersection of circle 8 and the vertical centerline, tangent to circle 8 at the upper side. | |

10. |
Construct the inscribed hexagon of circle 8, pointing up. | |

11. |
Copy circle 9 five times, to the other angular points of hexagon 10. | |

12. |
Construct a circle concentric to circle 5, tangent to circle 9 at the lower side. | |

13. |
Copy circle 12 to the center of circle 9. | |

14. |
Copy circle 12 five more times, to the centers of circles 6. | |

15. |
Copy circle 12 again five more times, to the centers of circles 11. | |

16. |
Draw the connecting line between the intersections of circles 5 and 9. | |

17. |
For clarity reasons, some of the results of previous steps are temporarily removed.Construct a circle concentric to circle 1, tangent to line 16. | |

18. |
Construct the inscribed hexagon of circle 17, pointing down. | |

19. |
Copy circles 5 and 12 six times, to the angular points of hexagon 18. | |

20. |
Construct a "two-points" circle, between the center of circle 1 and the upper intersection of circle 13 and the vertical centerline. | |

21. |
Copy circle 20 six times, to the angular points of hexagon 2. | |

22. |
Circles 5, 6, 9, 11, 12, 13, 14, 15, 19, and 21, are used for the final reconstruction. | |

23. |
Remove all parts not visible within the formation itself. | |

23. |
Colour all areas corresponding to standing... | |

25. |
...or to flattened crop, and finish the reconstruction of the 2016 Gerlingerstraße (Germany) formation. | |

26. |
The final result, matched with the aerial image. |
