I don't know about "odd" but I do know horrible...
Project Pluto was the first SLAM (Supersonic Land Attack Missile) worked on by the USAF. Two things made Project Pluto frightening. The first was how effective it would have been: the missile was designed to fly in excess of Mach-3, at very low altitude, using the then new TERCOM technology for low altitude high speed navigation. Even without a payload (I'll get to that in a minute) the missile would have killed anyone in a "target" area it chose to fly over: the weapon's mass and speed and altitude would've sent out a shockwave that would have simply crushed anyone not in an armored vehicle or bunker.
Of course, that's assuming the place flown over by the missile wasn't on it's target list. Pluto was planned as a robot bomber, a drone. It could be armed with up to 10 1MT hydrogen bombs. Part of Pluto's mission plan included post-strike strikes, weeks or months after the initial wars. Pluto was capable of staying in the air that long. How, you ask? Now we get to the really horrifying part.
Just in case the notion of a Terminator (or Berserker if you will) roaming around over an already blasted earth and continuing to pound the "enemy" with one megaton nuclear bombs isn't frightening enough, what enabled Pluto to keep on keepin' on like that was it's unique propulsion system. Pluto was a ram-air turbine jet that used air moving at hypersonic speeds over its
nuclear fuel elements for propulsion. Once launched, the air intake and exhaust system were open ends of a nuclear reactor. The Pluto missile was programmed, once it's payload was deployed, to slow to the point that it's fuel would become liquid. It would literally spray molten liquid plutonium across hundreds of miles as it slowed and crashed.
What kept us from deploying the ultimate doomsday weapon was three things: one, ICBMs were making great strides, in spite of successful ground tests of the engine it was kind of impossible to flight test it and, in the event of a war, the missile would have to fly over US or allied territory to get into position to open up its box of nightmares: it'd have killed us as well as the Soviets.
