I dunno if signifigant but it is entertaining :
"The most startling discovery was a book written in 1981, 20 years prior to the 2001 attacks, called "The Birth of Christ Recalculated". The author, Dr. Ernest L. Martin, claims to have calculated the exact date of Jesus
Christ's birth based on the celestial charts for that era. The date of Christ's birth, based on the famous Star of Bethlehem, is calculated to be September 11, 3 B.C.. Dr. Martin's findings have been accepted by many
scholars, theologians, historians, and astronomers. We also note that Jesus Christ has 11 letters. The crosses found standing in the ruins of the WTC, and the dominance of the number 11 in the 9-11 events, make this combination even more mysterious."
Oh, but don't stop there, it goes further....
