Estes twister (2008 model) rocket launch http://www.estesrockets.com Flying at what was left of the RAAF Williams Laverton base - https://en.wikipedia.org/wiki/RAAF_Williams#RAAF_Williams_Laverton_Base. Felt very sad but also somewhat privileged to be using a space that had such a great history in Australian Aviation. This space no longer exists and has been replaced with homes and a new suburb.
