Try it with your full address....when I entered the full address the aircraft went past our house........virtually anyway!! True!
It is a brilliant advert anyway, but add a British address and watch and see - sorry, but I don't know if the link will work outside Britain. ETA - It doesn't work outside GB ... so those "away" can type in my old Bude postcode - EX23 8DH
Also a very clever bit of viral advertising by B.A. Wouldn't surprise me if the original ad didn't win some sort of award in the future. BA launched a new Olympics themed advert which is quite clever BUT the REALLY clever bit is you can put in any UK postcode or address (or try both) and "thanks to CGI and Google Maps", the advert will include the B777 taxiing up your road!
