Hi,I was wondering if anyone could please provide me with details of the following Concorde tracks into and out of the USA.I'm not talking about the organised Atlantic Tracks called, Sierra Mike, Sierra Oscar or Sierra November but rather the routings used after those when heading into the USA and those when heading out of the USA before joining onto the organised tracks.I believe they are refered to as follows:For flights into the USA coming off of track Sierra Mike:SM1SM2SM2ASM3For flights leaving the USA before joining track Sierra November:1SN2SN3SNFor bi-directional tracks that are using track Sierra Oscar:1SO2SOSO4If anyone knows the fixes for these tracks or knows where I can find them on the web I would be extremely grateful. I have all the details for over the Atlantic and for the UK end of operations but the US side has proved impossible to find. I do already have the En Route High Altitude chart that covers these but it all becomes a bit blurred with courses merging as you get nearer the States and it would be nice to have the chance to fly these before she is retired.Any help will be very much appreciated.Regards,Steve.

If you Contact me at: [email protected]'ll send you some info. Regards,Andrew
