Sounds like the feds are treating the current "credible threat" as broad and shutting down all options. Anyone care to posit a scenario in which GA could threaten a nuke?

The GA plane has a smoke machine and draws special doodles in the sky, which are seen by the plant operator and she gets hypnotised into disabling the cooling subsystem. This is not a joke, this has been leaked from the top secret anti-terrorist docs.
