Never nice to look at but I guess to some it is acceptable hunting. Mindful that I have also seen video of Australian buffalo being herded by choppers and culled by paying sport shooters. Not long after I was in the NT hunting buffalo in the late 70's the choppers were brought in to cull the buff herds just as they have been used in NZ since the 60's to cull all our species of deer, chamois and tahr.

Of course the culls are usually carried out by professional shooters and in New Zealand's case the meat flown out and exported. These same choppers though have always been used to provide access to shooting areas for sport shooters, some who partake of shooting from the chopper, or using it to spot and herd game to their rifles.

The same old argument as to just what is classed as sport hunting or shooting. Comparable in many cases to 'farmed' and 'fenced' animals shot from or close to a vehicle in Africa but this gets overlooked in the romance of the modern African safari.
