Looks like the usual uninformed comments about the 380 surfacing. Two of sizematters statements seem a little wide of the mark, which makes me doubt the rest.
A380 has just landed at LHR. Last time I was there, the runways were 164 feet wide.
The reported CX comment was that they wouldn't think of ordering it until it could fly from LAX to HKG, all year and fully laden. Now I don't know whether it can or can't do it but that is slightly different to "fall into the ocean".
