It is a sad state of affairs that people had to be killed before anything is to be done about the lack of regulation at commercial DZs.
I always found it incredible that the operators advertise tandem jumps with scenic views etc yet they are not required to have an AOC & Chief Pilot. Everything about some of these places is the very definition of a commercial operation. The flight to height is a charter in every sense of the word and should be regulated as such.
An absolute failure on CASA's behalf (in my opinion)
