Rail systems would be nice, problem is the majority of the population would now have to drive to the station. And you've got to lay those rails, and build the infrastructure, in already built up regions. It's a problem with no easy solution.

This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
