ES, I follow your logic re OSD of two platforms at the time the mod was proposed [The weight growth mod]. I may have missed something as I understood from the SI that a Safety Case [for the Hawk seat] did not exist. It is therefore a big assumption that anyone ever did any ALARP detriment calculations. I would wish to be wrong about this.
I am sure there will be an audit trail for the decisions recorded on the F714/715 Cost and brief Sheets we operated at the time.
I love the term "Pillars of Excellence" you introduced. unfortunately I saw all the pillars crumble and pleased to be away from it all these days!
