  Quotations
  If Euston is not typically English, St. Pancras is. Its façade is a nightmare of improbable Gothic. It is fairly plastered with the aesthetic ideals of 1868, and the only beautiful thing about it is Barlow's roof. It is haunted by the stuffier kind of ghost. Yet there is something about the ordered whole of St. Pancras that would make demolition a terrible pity.

5. (transitive, figurative) To bombard heavily or overwhelmingly; to overwhelm with (weapons) fire.
  Quotations
  Yeah, if you think that was bad... having, obviously, here, being people in the modern day and knowing something about the historical tactics used at the Battle of Samar, we did have, at one point, the American battleline sailing itself into a rain squall, staying in the rain squall, using large numbers of destroyers (with, obviously, all their smoke generators) to increase the cover in the rain squall and maintain it when the wet squall seemed to start dying off, and, through that, they just went "Right, activate radar, hello everybody, we can see you, you can't see us", and plastered everything in 14-and-16-inch gunfire until everything was broken, burning, and not able to fire back, and then they popped out for the coup de grâce.
