Kapton, having been a member of the Filton MRA4 wing design team myself, it was indeed a view widely held within the company. The project was a politically motivated mash up against a wholly unrealistic initial budget. It was not helped by the different parts of Bae having to work together, despite them all having their own different ways of working and there being no trust between them. When things started to go wrong, there was an outbreak of finger pointing instead of collective working to solve any issues. It was by far the worst project I've ever worked on and should be used in business schools as an example.
