`  ::::::OK, I'll change the name to ``-ton`` in the notes.  I did some looking into it and I have to agree that kiloton, etc are all measurements of energy, and trying to reconcile the the mass of ``TNT equivalent`` is beating a dead horse.   About the elevation thing, yeah, I need to fix that.  I did it for the explosions themselves, and I just need to copy the code.  Thanks for pointing it out. The problem is that for all the blasts the elevation and height are at least theoretically distinct items.  But when they say that the John air-to-air test happened at 18,000 feet are they referring to airplane altitude (which is referenced to sea level) or distance above the Earth, which is how all the other tests (balloons, towers, tunnels, etc) are all measured?  And that goes by extension for all other rocket flights.  If you have any insight on that, especially as a former pilot, I'd appreciate it.  `
