If you looked away from the screen for a moment, you probably missed it. It was a quick smooch. Kate turned to her groom, said something with a smile, and the prince reached over, rather hurriedly, and gave her a very quick kiss.
Maybe that's why he kissed her again.
The second kiss came just before the Royal Air Force flyover. Another first on a historic day: two kisses on the Buckingham Palace balcony by a newly married royal couple.
All eyes were on Prince William and Kate as they emerged from the palace onto the balcony. Many among the boisterous gathered crowd and those watching around the world surely had one defining image in their minds: Princess Diana and Prince Charles' memorable wedding kiss.
