MarkD,
Your a cheeky monkey aren't you.
Telling one to shut where I am from will get you a wishbone on the mellon.
Its a fact. You ask any airplane financer or salesman.....RR powered 744s and 767s are valued at 20%-30% less than GE OR PW versions for than matter.
They have a blue book for aircraft. Look it up for yourself before you make a fool out of yourself.
This has nothing to do with the A380 EVAC test. For me that is not a B or A thing, that is my own personal opinion based on some years of experience. Just like you got an A**hole, I got the right to my opinion.
