As bad as they are, it's somewhat satisfying to realize how far lions have come in using Blender.  It was an extremely opaque program for so long.  

A plug was made in Blender for cutting windows.  The triangular segments had to be subdivided, but the square windows didn't.  Array modifiers did all the replication.

Boolean operations for the square windows worked, but not so much for the triangle windows.  The trick was subdividing the nose near the windows.  The latest idea for the triangle windows is doing it in a script, but it has to approximate the nose bezier curve.  A script can adapt to future designs much more easily than manually making plugs & tweaking boolean errors.

SpaceX has provided 3 variations of window designs.  Historically, all reusable spaceships have had thermal blankets completely coating the upper side with no distinguishing pattern around the windows.  The canards would definitely be coated in heat shield.

The useful array modifier video:

It requires frame advance & scaling up to see what he's doing.

The useful boolean video:

To use the sound driver while running blender:

blender -setaudio NULL

There was an effort to make godot surrender the audio driver

but it didn't work.  It's hard coded for ALSA in too many places.

2018 BFR notes:  118m or 8m taller than the Saturn V.  7m taller than SLS.  9m diameter or 1m narrower than the Saturn V.  .5m wider than SLS.  

Ship is 55m long, including 5m fin extensions, so the booster must have been lengthened to 68m.
