Interesting footage of the breakup sequence - clearly there's a failure of the left wing outboard of the engines fairly early in the breakup, followed by a rapid roll onto it's back with the forward fuselage & nose breaking away and the centre section exploding.
Anyone know - was the left wing the initial, primary failure? Think I read somewhere that it was one of the canards that failed first, but certainly in the earlier 'rooftop' shots the canards don't seem to be extended. Doesn't mean they weren't for the final manoeuvre though I guess.
