I suggest ignoring the contribution by 101917 on this thread, they are presumably able to restart that particular hamster wheel on the main Mull threads should they really wish.
On Chug's perennial point about the baleful influence of senior RAF officers and the compliments to Engines on the much better influence of senior RN officers, I should point out that the current 3* air engineer at DE&S is an admiral. An opportunity for those who know of what they speak to write in and get the relevant policies changed?
