Strobe illumination
For many years I flew into and out of LCY. One of the things that was easy to to miss was Canary Wharf, purely because of the high intensity strobe. When in cloud you made sure that you were on track because knew you were near the building. But would this be of any help now? There are now so many tall buildings and structures in London that putting standard strobes on them all might make it more rather than less confusing. Maybe flash and colour coding like lighthouses may help?
