Accompanied by Princess Anne, Queen Elizabeth's coffin will be flown from Edinburgh, Scotland, today to London. The coffin will initially be taken to Buckingham Palace before it is moved on Wednesday to Westminster Hall, where the Queen will lie in state until her funeral on Sept. 19 at Westminster Abbey. In Edinburgh on Monday, the Queen's four children walked silently behind as a hearse carried her flag-draped coffin along a crowd-lined street from the Palace of Holyroodhouse to St. Giles' Cathedral for a service of thanksgiving. The coffin remained at the cathedral until today so members of the public could pay their respects.
