We had an excellent weekend launching rockets with Damien Hart from Damo's Water Rockets. It was good to finally meet him and his family in person. The weather was well behaved and so were the rockets. (Well mostly)
We took turns in launching rockets, and as a grand finale we combined Damo's booster with our sustainer for a two stage flight.
The full details of the flight day are available here:
and Damo's great write up of the day is here.
We'll have to do that again.
