bushveld, as OP I owe you an explanation. Your thread is entitled RAF Chief Engineer. The reason that no-one can direct you to him/her is because the post was scrapped in 1994 (ie the same year as Mull). Excerpt from the Nimrod Review:
Airworthiness responsibility
12.6 In 1994, the CE(RAF) role was transferred to the Senior Engineer Officer at RAF Logistics Command. This was
either the Commander-in-Chief (CinC) of Logistics Command (an RAF 4-Star or 3-Star officer) or, in the event
of him being a non-engineering specialist, his Chief of Staff (CoS) (an RAF 2-Star office). The CinC Logistics
Command was a member of the AFB and, through the CE(RAF) office, he had ‘lead command’ responsibility
for RAF-wide airworthiness policy.
Mr Haddon-Cave QC who wrote the Review recommended that the post be re-instated.
BGG, No rant. I'm sorry I'm starting to annoy you but Trenchard knew the value and worth of trained engineers, hence his brats. His successors today seem not to.
