As many others over here I try to keep track of all my flights and put as much info as possible in a nice little Excel spreadsheet. For my flight YYZ-LHR I'm having some problems with identifying the correct departure RWY. It must have been either 33L or 33R. I think it was 33R but I'm not 100% sure since I'm not familiar with the airport and it was already night by then. Maybe somebody over here has access to this information?
Thank you very much in advance,
