A UXB in Exeter

Not much info available as to why they decided to demolish in situ. Presumably they decided defuzing was too risky. From what I can see via satellite views the bomb was found on an undeveloped plot adjacent to student residences so already had a fair safety distance. Digging trenches around the UXB helps reduce ground shocks and bagging and heaping a sand mountain on top further contains blast. Nevertheless, it was a high-order detonation and the subsequent damage reported as light so relief all round! I bet the crater is big......

Some info on blast, crater, damage, projectiles, etc in this report.

It didnt look very "controlled" in the video I saw on twitter.

It was 'controlled' in the sense that physical precautions were taken to limit the blast. Usually 'controlled' means using a small focussed charge to split the bomb case with the intention to cause a low-order detonation (only part of the main filling detonates) and remove the remaining filling by steaming out. But, if the original bomb fuze has not been extracted that could fire and high-order the lot. It looks to me as if, due to the disruption caused by evacuating residents from the area, that a decision was made to demolish in situ to conclude the operation speedily and accept the consequences. Possibly, the fuze was protected by an anti-withdrawal device. The team would have X-Rayed the case to determine the best course of action.

The initial response seemed to be from the RN EOD unit based at Plymouth, however noted a day or so ago that the BBC claimed the "Army" had detonated the bomb. Would that have been the Royal Logistic Corps or are the RE still involved in EOD?

My understanding from the local news reports is that the RN BDS from Devonport did the initial preparatory work and 'experts' from the Royal Logistical Corps did the detonation.
Some links to local reports show a few more pictures of the scale of the damage.
