Except the part about "civil sevants in procurement" (sic)
In the mid90s, civil servants in procurement were repeatedly warning of under provision of risk funding, and particularly noted the issues regarding the re-use of the old fuselages. Last time I saw the files, they were on a Bernoulli drive at St. Giles Court, don't know what happened to them.
Like wise, the investment appraisal conducted by civil servants in procurement did not identify the Hawk 128 as the best value for money in the AJT competition, but the recommendation for the Italian job was over-ruled by Ministerial direction.
