Verifying that the 9/11 date will be inscribed on a separate section of Memorial Wall that sits in the exact position of the star on an Islamic crescent and star flag
At the bottom of the Sacred Ground design page is an elevation view of the two part Memorial Wall that follows the flight path down to the point of impact:
The lower section of Memorial Wall (on the left, and closest to the crash site) contains 40 translucent panels, inscribed with the names of the 40 murdered heroes. There is a gap marked "trail," then a separate upper section of Memorial Wall, with three translucent blocks inscribed with the 9/11 date. Click picture for larger image. (There is a 44th translucent block on the flight path at the upper crescent tip, at the end of the Entry Portal Walkway.)
The trail that divides the Memorial Wall is visible on the Crescent of Embrace site plan:
Red arrow: the centerline of the crescent (points
to Mecca). Purple: the path that divides the Memorial Wall into separate
upper and lower sections. Aqua: the separate upper section of Memorial Wall,
inscribed with the 9/11 date.
Just by looking, you can see that the upper section of section of Memorial Wall
is centered on the bisector of the giant crescent, placing it in the exact
position of the star on an Islamic crescent and star flag. (Most Islamic flags
are based on the
Ottoman or Turkish
flag, which places the star on the centerline of the crescent.)
The date goes to the star on the Islamic flag. The date goes to the
terrorists.
To be technical about fact checking from source documents, just open up the site plan PDF, zoom in on the giant crescent, and print. Then take a ruler and a square, form the bisector of the crescent, and see where it passes through the upper section of Memorial Wall. If you are accurate, you should get what you see above.
