Advert in to-day's Torygraph.
There's a two page spread in to-day's Torygraph which is along the lines of, never mind about a third runway at Heathrow, just extend.
Basically the proposal is to extend one runway and use it in two sections with a 380 metre space as safety zone.
Erm, forgive my ignorance about this - no really - but am I to understand that one aircraft will be landing at one end of this enormously long runway whilst another is taking off from the other end. What happens if the landing one suddenly has to overshoot and go around again? What position does that put the taking off one in?
