 The [V-2](https://en.wikipedia.org/wiki/V-2_rocket) has a significant place
 in the history of rockets, and Bdale always thought it would be cool to build
 and fly a model of one.  After learning how to make APCP research motors and
-experimenting with Everclear (which has visible flame characteristics 
-reminiscent of the LOX and ethanol fuel used in the original V-2) the 
-idea became even more appealing.
