We've worked on the Avaition and Communications merit badges during the last two months.  To actually earn the badge, however, you must complete the merit badge worksheets and meet with Mr. Ladd to discuss what you've learned.  The merit badge worksheets are available on the MeritBadge.org website at http://meritbadge.org/wiki/images/0/0c/Aviation.pdf and http://meritbadge.org/wiki/images/1/19/Communications.pdf
