Best of luck to them getting that purchase order past Congress. I seem to recall one of our friendly neighborhood clones--er--TSOs mentioning that the reason BKSX had fallen out of favor was because it couldn't be made to work with ATD, and that when that hurdle was solved, we'd see more BKSX orders "to encourage further development of both technologies".

The TSA can say or do whatever they think will make Chertoff's pants get a little wetter and his wallet a little thicker, but I just don't think they'll be able to get any more BKSX orders through. MMW, sure, but BKSX has too many inherent political concerns behind it for any lawmaker who values their job to sign off on a budget that orders them.
