I have just added another feature to my simulator.  It can now model
the heat of reentry.   Basically the shock wave compresses the air by
a certain amount and compressed gasses get hotter.  It is more
complicated, and I have a full web page of explanation and links in
"spacetethers.com/shockwave.html".  There are limits to the accuracy
of this, but for the lower temperatures that my dream rocket reenters
at, this seems good enough.

So the simulator can now do tethers, projectiles, rockets, atmosphere,
drag, and reentry heating.  Again, it is a Java applet, so it is free
and easy to run and the source is posted on the site.

The site is http://spacetethers.com/

The last three examples, with the word "reentry", are showing reentry
simulations.  Just click on one and then "start simulation".

Any requests for features?  :-)
