777
Not buying 777's will probably go down in history as one of Q's biggest strategic mistakes.
Having worked in engineering for a long time RR engine failures have definately increased. The creation of specialised boro section helped reduce failures, since boro section is still operating we need to look at what else has changed for the answer.
After the 08 pia, unfortunately Q has recieved intense media scruitiny.
If only G.D had come to an early agreement this may not be happening now.
Obviously anything to do with Q and aircraft safety sells papers.
