Just a quick plug for the usefulness of APRS. I provided instructions to the Boxer rescue people on both ends on how to use APRS tracking on the web.
They watched us dropping breadcrumbs across the countryside and headed to the airport when we were close - took headwinds and tailwinds (and late departures) out of the equation.
I've posted on the P&P board about APRS and some of the guys are going to add it.
