shoey, to echo zkdli , you did not exactly do a great job of covering the controllers identity.
And secondly, if this piece is concerned with the safety of the travelling public in the world's busiest airspace, then why did ye send the BBC chopper up into the mix....
Havent the ATC guys n' gals in that part of the world got enough to be doing without a Beeb helicopter at low level, looking for pretty shots of Heathrow
Just my 2 cents (excluding taxes, fees and charges)
