Horse & Rider Were Solo Stumble in Royal Wedding Proceedings

Over the course of William and Catherine's fairy-tale wedding day, everything seemed to go exactly as planned, without so much as a stumble.
But one horse and rider in the grand procession from Westminster Abbey to Buckingham Palace took one for the team.
The horse, a member of the Household Cavalry, and the trooper took a spill after the animal was spooked en route to the first reception of the day. Both were uninjured.
"It was just a complete accident," a source tells PEOPLE. "They were trotting 'round a corner and because they were on the outside, his horse had to be moving at a fast pace and this led to it losing its footing as it went 'round the corner."
Luckily there are no hard feelings toward the four-legged member of the cavalry who, along with the trooper, will resume their duties in due course.
