I love the description there following the list of cargo: "a highly explosive mixture" ... in the same way 
that Hamlet had "a bit of a disagreement" with his uncle!  :-)

But not actually an explosion, I think?  I have a picture of a map of London with the Tunguska blast area 
overlayed on it - almost all of Greater London, out to the M25, would have been destroyed if it had hit at a 
critical point near Dartford.  In fact, I'll upload it so others can see:

As it happens, I live just outside the marked area! :-)
