My recollection is 10kg per wingtip. 10 kg of Uranium (or Tungsten) would be a bit over half a litre at a guess - a quite trivial volume compared to the size of a 737 wing. Why is density so important? Why is a 10kg (half litre) of Tungsten so much better than (say) 10kg (2 litre) of rock? Michael W.
