I liked the hidden nugget about the quality of engines coming from RR/BAe. Bang on the money, the product coming from them was shocking. Wasn't unusual to go through 3-4 engines on an engine change in KAF.
In GW1 at Murharraq, our 13 aircraft went through 74 engines in five months. These were predominately oil consumption issues which modded gearbox breather carbon seals fixed.
When I first started on Tornado, the mean time between bay visits was 176 hours. Post single crystal HPT, this went up to 400-500 hours. When I found myself back on Tornado as a civvy a few years ago, some engines were exceeding 1000 hours between shop visits. Just after that, the RAF RB199 bays were closed and work transferred to Bristol. I actually declined a temp job offer at Bristol getting the RR guys up to speed.
As far as you can say here.... what sort of problems are the sqns suffering with the RB199 these days?
