The design for the memorial calls for a red crescent that Wretchard at the Belmont Club has calculated would point towards Mecca. You can do something about it though. Let the U.S. Park Service know that the design is unacceptable here.
My comment to the Park Service was as follows:
Please reject the "crescent of embrace" design for the memorial. The use of a crescent would come too close to making it a memorial to the Islamic militants who hijacked the plane and would, thereby, betray those brave passengers of Flight 93. Why not something based on "Lets Roll" instead?
My comments are much more tame than my true feeling on this.
Mark Steyn has weighed in.
