The Royal Navy towed a 150 year old Napoleonic ship-of-the-line out into the English Channel and blew it up because post-war Britain was too broke to preserve it. This unlikely event was recorded on BBC television. Rather surreal. https://www.youtube.com/watch?v=OUOBQhojEfE The ship is flying both the French and English flags because she was initially a French vessel taken as a war trophy. https://en.wikipedia.org/wiki/HMS_Implacable_(1805)
The sailors saluting are on the deck of a newer battleship called the Impacable.
