Bomb disposal
 

London City airport has been closed all day following the discovery of a WW2 bomb.
I have been asked why a bomb in London would be defused by a Royal Navy Bomb Disposal Team rather than army?
For the benefit of my civilian friends, all 3 services have a Bomb Disposal capability.
Who deals with the device depends on where the bomb is found. The Royal Navy deal with anything below the high water mark, the Army deal with anything above the high water mark and the RAF deal with bath bombs and fizzy pop unless there is a danger of spiders when they call in a service with more seniority... such as the Scouts.
