Sorry Wallabie, maybe you misinterpreted my post. I did not suggest that "Because you are Concorde" you should get whatever you want. My statement is applicable to any aircraft and any captain. You do not accept a clearance, TOW, loading C of G or any other thing that may put you at greater risk than necessary. I also stated that the loading/performance discrepancies may not have caused the accident themselves. I don't think they "caused" the accident. But there is no doubt that all contributing factors however small must be taken into account. As stated earlier, interesting to ponder what an 8 knot headwind instead of tailwind may have produced. Just because an aircraft, (any aircraft) has "managed" to make it before in similar conditions does not mean it's a good idea to repeat the excercise does it?
