Sorry just need to reply hereFirst, as to who is responsible.Very simple answer. ATC might claim that they have many responsabilities, and this is true, aircraft separation like this is essentially ALWAYS a pilot's responsability.On the ground, the rules are clear. You are in charge of your airplane, must know it's dimensions and what it can or can not pass. The rest is plain BS and usually there are more 'rules' but they are merely for insurance purpose.So it's quite clear, the Air France did not properly judge the position of the CRJ's tail, which makes them 100% to blame for this. It's the same in your car, if you pass a green light, you still have to make sure the cross roads are clear for you to pass!Secondly: concerning the speed.I can only agree to the 20kt calculation. measuring the time between the tip of the nose passing and the mid of the a/c passing is a valid way of determining this. Also, i don't understand where you guys get that 'depth' aspect? the length of the A380 is a very absolute figure, if you reference it to a fixed point there is not 'depth' aspect at all.Thirdly: airbus vs boeingGrow up people, they both make great airplanes and considering the enormous amount of time they have been in the air they ALL have a pretty damn good safety record. To not fly one of them show's ignorance imho(hey it's my opinion ;) )Fourth: A320 HAbsheim crashThere are many things to be said here but for me it's quite obvious:The aircrew made some VERY poor judgement calls, BUT if the technology had done what it should've done they would NOT have hit the trees.It is part of an enormous coverup by Airbus because the airplane was just released brand new, one of it's first flights too.There is very convincing evidence that shows the FDR/CVR have been replaced between the crash scene and the initial detainment at the official's office. There are a lot more troubling items such as an OEB wich was to be release days later concerning a glitch in the ATHR vs FADEC communication and many more (google it and brush up your french ;) )don't get me wrong, not against airbus here at all (heck i fly the real thing every day)food for thought.and mr. 'if it aint boeing i am not going'... really? :( if your mother was dying in a city far far away and you'd only be able to take an AIRBUS flight there you'd let her die alone? :( :( ;) (not the smilies please)Lenny

Airbus for ever!!! Their cockpits are so nice... I hope Boeing would use the same colors instead of that yellow, orange or whatever you called it :(.
