I can fill in a couple of details to make sure everyone has the facts.
The plane operates VFR and IFR depending on the prevailing weather.
There should generally be no approaches done as cloud is above MVA
There is radar to the ground so traffic is always seen.
The operator has a cloud manual
If jumping through cloud you may not get a view the entire time but you will for the entire canopy ride which is completely clear of cloud
There will be always pressure from operators to get the job done no mater what. Its up to the pilot to have the sack to follow the rules and fly safe
There was a risk assesment to get the cloud manual.
The main thing that needs to be highlighted here is communication. If you are in the lane from laverton BOM tower or rickets point. Just communicate. If you can't divert around during a drop for whatever reason the pilot will just wait. The main thing is awareness not just for parachutists but for other aircraft in the lane.

Safe flying!!!
