There will be substantial disruption in Falmouth (Cornwall) today due to a 250 pound WW2 American missile being discovered- there is an operation this morning to defuse it- https://www.bbc.co.uk/news/live/cvp8dr250ennt
So Falmouth is best avoided today until the area is declared to be safe.
UPDATE- The bomb has now been removed out to sea, where it will be exploded in deep water in 6 days time, due to an unstable 144 hour fuse which is potentially ticking due to the effects of the removal.
The cordon has now been lifted, and people allowed back home.
