Following the fire in Birmingham caused by a Chinese lantern ( http://www.bbc.co.uk/news/uk-england-birmingham-23150245 ), can the weather ballooning community come up with an alternative?
The alternative would have to be small, cheap, non combustible, and recoverable.
Here is my pitch:-
100g pilot balloon with a 50g sms tracker and a large glow stick. Of course I don’t know the impact of pressure on the glow stick but it is a good starting point – launched with CAA permission of course.
