A full house heard Andrew explain just what High Altitude Ballooning meant.
How the hobby started from interest in weather balloons and developed into
a sport which includes its own dedicated software and equipment.

A short history followed as Andrew told of early pioneers and modern day
flights which included some with human payloads seeking altitude heights
and parachute jumps. Modern balloons can carry equipment to provide
telemetry to record and transmit heights, wind directions and temperature
as well as video during the flight. This transmitted information can be
monitored live and plotted online by others interested in following flights.

Since some balloons can attain great heights, Andrew explained the
regulations with regard to size of balloon, launch location and wind
direction so as not to interfere with aircraft flight paths and other no
fly zones which include motorways and built up areas.

The equipment Andrew has used was on display and working, sending telemetry
recorded during an earlier flight, but this time including photos of the
assembled club members.

Questions might have continued till midnight if time hadnt been called!
