Someone associated with UCL (such as Jon Crowcroft copied here) can
give further details/corrections, but this is my understanding:

At the end of the ARPANET project at University College London
(UCL), their IMP was decommissioned and basically ready for the
scrap heap. There was only one problem: Since the equipment had been
imported without any duty under a research agreement, and since
returning it to the US would have been expensive and pointless,
representatives of Her Majesty's Government was contacted to have the
IMP officially destroyed.

(I have this image in my mind of a warehouse where they temporarily store
contraband before it is burned...)

Jon can hopefully tell us more :-)
