I've talked recently to the guy working himself to death trying to make it work. So to clear some of the pointless claims here with info that came to me from the horse's mouth and then we get on with complaining about the software instead:
The specification was set by aircrew.
BOCS exceeds the specification originally set (alledgedly, the crewing module was specified by 13 bullet points!)
Each RAF ProjO (we are on the 3rd) has been aircrew.
The software is commercial and has been designed by the companies producing it. (Jeppesen is US and APM is Swiss).
The bloke working for the current ProjO and trying to solve the problems (ex aircrew) is surprisingly frank about the project.
We first looked seriously at receiving it this Jan, about 3 weeks before it arrived.
