this issue was first broached, we started vetting issues pertaining to
astronomy. This change would surely cost us millions of dollars.
Criticizing the one group who have taken the time to look is rather

You have mentioned planes, trains, shipping, power and military
applications. I gather you have experience with these projects.
Somehow it is my job to vet your systems from the outside? At the

gambits, the one topic that gets a rise out of the group is a simple,
heartfelt suggestion that proper system engineering practices be

System engineering != red tape

Far from stalling, separating problem definition and requirements
discovery from a tradeoff study of possible solutions is the fastest
way to proceed.
