Thanks to everyone that supported the EOSS-267 flight yesterday. It was a resounding success in several ways.  We shook the cobwebs off of our knowhow and  tracking stations, we successfully qualified several new payloads, and we had some new members join us in the chase!  We had several University of Colorado CBASE students join us for the launch and recovery to help hone their skills for assisting in planning, launch, and recovery later this year.
