BAE 89% on budget --- after being paid for features that are not delivered
It might be the case that 89% of BAE's programmes are on budget, but this may be a meaningless statistic if in reality the tax payer is paying massively inflated prices for features (such as "adaptability") that are not actually being delivered.
To some, the "89% on-budget" claim is not very surprising in a context where contracts and sign-off conditions are being negotiated and approved by a body and/or individuals that seem to align themselves more with the interests of the contract holder than those actually paying the bill.
This the problem with high-level complicity in corruption and fraud; it's just too easy to manipulate the official statistics etc. so that outwardly everything seems sufficient fine to rebuff casual enquiries, and divert attention (AKA "doing an Obi Wan").
