Planes are banned from flying below a certain altitude over parts of London, Edinburgh and Balmoral Castle in Aberdeenshire.
Kites, small balloons and parachutes have also been included in the low-flying ban, which will last until the end of today in Scotland and until after the Queen's funeral down south. The ban has been implemented by the The Civil Aviation Authority (CAA), who say that it is part of wider security arrangements.
They say that a "protective blanket" will be created over the restricted areas while the ban is in place, reports the Mirror. In Scotland, aircrafts are not permitted to fly below 6,000 feet above mean sea between Balmoral Castle in Aberdeenshire and the Palace of Holyrood in Edinburgh until 11.59pm on Wednesday.
