Comet aircraft coming in to land

A jet aircraft either coming in to land, or taking off. At first I couldn't think what aircraft it was and then, after a bit of research on Google (looking for 4 jet engine aircraft) I found a picture which reminded my why I thought it looked familiar. This is the famous De Havilland Comet. I wonder if this one had original square windows which caused the problems or the more modern version with round windows.
