It may be a suitable time to comment on the covering for the coffin. From time to time requests come up for information on how to borrow or buy an RAF ensign to cover the coffin at an RAF funeral. In fact the RAF ensign should not be used for this purpose, the correct flag (if one is required) is the Union Jack (or Union Flag if you wish to be pedantic). There is a website offering RAF ensign coffin drapes for sale, but these people are either ignorant of the convention, or just ignore it.
