Hey, bob, what are we going to use for this spacecraft guidance software? Didn’t we have some old guidance code laying around? Let’s just reuse that, it worked great!
It's hard to fault his logic? If intended, nice pun. If not, nice accident.
But, yeah. Increasing memory costs a predictable amount in hardware redesign. Plus some additional cost per unit, but missiles are a low-volume item. Fixing all (or enough) memory leaks costs an unknown and possibly open-ended amount of software time, and may introduce new bugs. In this instance, the trade-offs say that increasing memory is probably the better path.
