<comments>Aerotech F21W (White Lightning) RASP.ENG file.
File produced Jun 22 2004.
The file was produced by scaling data points off the
thrust curve in the Tripoli.org motor pdf file.
The F21W cannot be found on thrustcurve.org.
Hence the amateur file production.
The file was created by Stan Hemphill
