Overview

The objective of this fin can is to attempt the first potential flight candidate fin can for Hermes III. This fin can implements the lessons learned from the first fin can. It includes steel leading edges, a different laminate stack up, and the correct fin geometry. 

This fin can is the second in the series of 3 fin cans for Hermes III (Rusty, Dusty, and Crusty.)** This is the story of Dusty Crusty.

**Originally, Dusty was supposed to be the 2nd completed fin can, but a series of unfortunate root bonding accidents resulted in Crusty being completed before Dusty. Therefore, despite the fact that the overwrap for Dusty was done a week before the overwrap for Crusty, Crusty is now referred to as the 2nd fin can.
