I guess more and higher buildings in the way of the Heathrow flightpath would give greater justification for the idea of Boris Island airport in the Thames estuary.
That was my initial thought too, a 5300 foot building under the flightpath just a handful of miles distance, aircraft have to be around that height over central london surely - maybe they will start featuring the city approach to Heathrow as a sort of roller coaster ride descending from 10,000 feet straight onto the runway in one swoop ?
