High Altitude Ballooning Guide

Radio amateur *Dave Akerman M0RPI* has published his guide to High Altitude
Ballooning, From The Ground Up (and back again)

High Altitude Ballooning makes for a challenging project that sometimes
turns into an engrossing hobby.  Whilst it’s not “rocket science� it does
encompass a wide range of fields (sometimes literally) and there’s a lot to
learn before you send your first flight up into the sky.
