I was at LHR on Tuesday and got a few very crappy pics (on account of the fog). I was taking them from the Northern Perimiter road as the planes were waiting to take off on 27R. I was taking them through the wire fence that runs the length of that road. I was only there for 15 minutes due to the weather but was I risking it as far as the police moving you on? Has anyone else taken pics from there? Any trouble? I thought it was a pretty good spot for line-up shot and would like to return on a sunny day.
