747-436 - totally agree with you, and I'm still amazed that TfL are totally dismissive of the ideas I put forward which would solve sveral major problems at once, and put LHR back into its rightful position as one of the most important EU hubs for air AND HS2.... its actually really simple and fits in perfectly with svseral other major schemes in the area, and believe it or not would probaly please most of the environmentalists around Heathrow!
