	How much commonality is there between the RB211-524 used on the
747-400 and the Trent 700 that may be used on the 747-500X/600X? In
particular is there likely to be any advantage to Rolls due to there
being a few airlines that have has Rolls powered 747s but not Trent
powered 777s that might buy the 747-500/600X. (I am thinking British
Airways and perhaps Qantas)
