A pint of whatever JFZ90 is on please barman !

OK, my comparison is very rough (VISTA metrics from 30 secs on wiki), but I think demonstrates a valid point. Which bit are you struggling with?
And how many of those 50 million lines of code are safety critical, which makes them more expensive per line of code. (Clue - ZERO), whereas Nimrod MRA 4 has more than a few.
Quite - forget now the cost deltas between high integrity and 'normal' code but figures of 4-10 times more expensive to produce seem to ring a bell (especially so in the UK after certain domestic safety favourites such as semantic analysis have been bolted onto the coding standards the rest of the world seems to agree is sufficient for critical code, n'est pas S_H?).
