(CBS News) LONDON - It's back to business here.
Queen Elizabeth II resumed her royal duties Wednesday, following a massive, four-day party to mark her Diamond Jubilee.
Official celebrations came to a close Tuesday in grand style.
Less than 24 hours ago, London's streets were lined with more than a million people.
Now, the party's over, and the clean-up is under way.
The queen watched from a Buckingham Palace balcony as Royal Air Force planes from World War II, and the RAF acrobatic team flew by. It was the Jubilee's final hurrah after four days of spectacular pomp and pageantry.
Earlier, the 86-year-old monarch smiled and waved at a sea of well-wishers, many dressed from head-to-toe in the colors of the British flag. They filled the avenue leading to the palace to celebrate her 60 years on the throne.
Then, it was Her Majesty's chance to show her deep gratitude and appreciation.
In a televised speech, she said, "The events that I have attended to mark my Diamond Jubilee have been a humbling experience. It has touched me deeply to see so many thousands of families, neighbors and friends celebrating together in such a happy atmosphere."
At a thanksgiving service in St. Paul's Cathedral earlier in the day, the queen cut a solitary figure. Her husband, Prince Phillip, has been in a hospital for two days being treated for a bladder infection. Though the prince is reportedly feeling much better, the queen was said by her son, Prince Edward, to be missing him.
It wasn't just Britons wishing the queen well for her Diamond Jubilee.
President Obama had a video message for her majesty, saying, "As a steadfast ally, loyal friend and tireless leader, Your Majesty has set an example of resolve that will be long celebrated."
