After Dave heads out for flight testing, Melissa gets an idea. She guesses that the cell phone data problems yesterday might be because she is down low amongst all the masts in the marina. Maybe interference? So borrowing from what we used to do in Central America when signal strength was problematic, she puts the cell phone hot spot device into a dry bag and hoists it up the mast using the spinnaker halyard. Sure enough, that improves signal strength enough that internet is fast the remainder of the day. Meanwhile, for Dave, test flights go smoothly, and they finish up! A new piece of gear is ready for certification. Whoo hoo. Great birthday present for Dave today!
