I find this hard to believe since C-5s are military planes still in
active service. I doubt the drug smugglers have gotten hold of any.
What is your source for this assertion?

     Another example
    would be a supersonic cruise missile with a nuclear-reactor powered
    jet engine (since it would only fly once, and has no crew, nuclear
    propulsion seems feasible).  Nuclear propulsion might permit the
    cruise missile to fly fast enough to avoid most defenses yet still
    be able to fly intercontinental distances.

Why would you need nuclear power?  Ram jets wold probably suffice, at
least according to DARPA.

You'd want nuclear power for several reasons:

  (1) Range.  Currently, cruise missiles must be launched fairly near
      to the target, because of fuel limitations.  A nuclear powered
      cruise missile could be launched from anywhere.

  (2) Speed.  Current cruise missiles are subsonic; at high
      speed the fuel consumption is unacceptably high.  A nuclear
      powered cruise missile could go much faster, making it harder
      to shoot down.

  (3) Size.  Ignoring shielding, one might hope to make a reactor
      smaller than a chemical engine & tanks of similar performance.
      A smaller target is harder to shoot down, and has lower drag.

  (4) Power.  With a more powerful engine one can add armor to the
      missile, reducing the effectiveness of antimissile weapons.
      Also, current cruise missiles must attack their targets on
      flat terminal trajectories, because they have insufficient
      power to climb & dive at steep angles.  A nuclear powered missile
      would avoid this problem (although adding a short burning chemical
      rocket to normal cruise missiles might also solve the problem).

Obvious objections include: (1) maybe high power nuclear engines are
hard to build, (2) the electronics will have to be shielded to some
extent, (3) testing the missile will be more difficult, (4) the
radiation emitted by the engine may make detection easier.
