There has been much speculation over the years about the possible effect of the whole lot going up at once. These range from total destruction of Sheppey to a minor tidal wave. A lot depends on the state of the tide and the amount of silt covering the wreck but one theory is that the cushioning effect ot the sand below the hull would improve matters. I don't know if any computer modelling has been done on the likely outcomes.Whatever the magnitude of the explosion a lot of people will be affected and probably cause the Thames Barrier to be raised.
There is a regular survey of the site and I think there has only been one dangerous incursion on the danger area in the last 10 years, the others being solo efforts by small craft.
Not sure what the sound will be, it being underwater, but previous explosions near us have sounded like low booms but they were only demolition charges, so a little bit smaller.
I wonder if any estuary port proposals were vetoed due to the dangers.
The other reason for posting again was that danger buoys seem to be yellow, yet an obvious choice would have been red. I know red is used for other purposes but yellow is less visible in poor light or mist. Still most vessels carry GPS navigation systems so probably irrelevant anyway.
I seem to recall BBC Coast covered this in an episode. While I was looking for it on Utube (to no avail). I saw some prat had overflown it with a drone. My apologies to them if they were licensed etc etc but really now.
I can't see a drone collision doing much. If it were to carry a grenade, or similar, likewise. Think of the power of an average wave, all day, most days. If the powers that be want to blow it up in situ, I'm sure it would cost the taxpayer zillions in "consultancy fees" "exploratory work" and the risk assessment would outweigh the ship.

I think one TV filmed near the wreck and were very quickly challenged by a boat sent out by the CG(?).
Is it marked on AIS? A wreck can be marked by virtual AIS buoys from a transmitter onshore.
