Jabawocky,
There was some fierce stuff in the second comment to this item in Plane Talking which sounds like inside info.
Qantas bites tongue over its Dreamliner nightmare - Plane Talking
However in the next item Sandilands goes on to ask if that comment might have been from Captain X who I've seen pop up and get flamed on Airliners.net
Then today he makes a reference to heat retention by composites in the undercarriage not being factored in.
Do the comments by Markus 45 about what has been going wrong stack up?
I want to fly on a Dreamliner but you have to wonder how it could take so long from building it to flying it.
