Does anybody remember the Concorde departures? From memory, I know that it was called "Sardi Seven". I presume it was used to get the aircraft over the Atlantic ASAP so it could reach supersonic speed quickly. Soon afterwards, the aircraft would enter an airspace called W105-A. My question is did any subsonic aircraft also use "Sardi Seven" for departures and was the Concorde the only passenger aircraft allowed to use the airspace W105-A ?
