This footage shows images of the lower Murray, metropolitan Adelaide, the Coorong and almost all the way to Port Augusta at the top of Spencer Gulf, from an altitude of 33.7km (110,800ft). It was captured using a camera flown aboard an amateur helium balloon flight undertaken by the Project Horus team based in Adelaide. More information can be found on the project website projecthorus.org/
If you listen closely, you can hear the balloon burst at the 00:34 second mark, followed by the sound of the wind as the payload begins it's decent back to earth.
This is a stunning reminder of how small we really are against this vast continent of ours!
Note - this is not something you can do out of your back yard. A long process was required with CASA to seek approval for this project.
