You are of course right its the GP7200 on the A380 and GenX on the 74/87 my mistake
The CF6 is by all accounts a fantastic engine and as you say still around doing its thing.
PW has all but disappeared from the civil scene having to go into partnership with once fierce rivals in order to survive. I think the only a/c that it has a stand alone engine on is the A330 and its Geared Fan in the final stages of development.

I forgot to mention yesterday that BA was the only airline at one stage to operate all 3 engines on its 747's. When BA bought British Caledonian in the late 80's they already had the 100's with PW JT9D's 200's with RB211's and the BCal 200's came with GE CF6's but were sold quite quickly.

BMW came on to the scene with the BR700's (used on the Global Express, GV/G550 and Boeing 717) in the early 90's and as far as i know have little to do with the Trents.
