   Maybe this would be a good justification for reviving CRAF -- complete
   with penetrator. :-)

Hmm, last I checked I don't think CRAF was up to a delta v of 50 km/s
or is this a incipient resurgence of the never-ending ion drive thread ;-)

   Of course, it's too late for Swift-Tuttle, but surely we can find
   another Earth-crossing comet which is posing an imminent threat to
   all life on the planet...

Probably can, but most will be dominated by Jupiter perturbations,
Swift-Tuttle doesn't look like it's going anywhere (caveat: this is
guesstimate from eyeballing the orbit parameters, somebody will
actually have to find out for real bu integrating the sucker),
ie it will keep coming by until it hits as far as I can tell, but
that's most probably a few million years off...
