A friend who was something senior (don't want to drop him in it) in Clansman radio production way back when tells me that one of the suppliers basically told the MOD to shove its contract after enduring something like a thousand mod revisions after the production line had started. No amount of money could compensate for the fact it was making the company impossible to run.
Mind you, he has plenty of war stories.
As for Bowman: has anyone written that story yet? I'd love to read it. If not, I'd love to write it!
