I once spent an afternoon with the principal/owner/CP of a very well known helicopter school with a view to transitioning to CPL(H). I got to see day to day operations, hangars, current students, the various endorsements they offered, how they generally operated and him displaying some very fine a/c handling. I was impressed... until I heard him take a phone call. He was speaking with someone about cattle mustering training and he admitted he did not have any endorsements or experience to do so but was keen to do business. All the good impressions I had gleaned to this moment dissipated in an instant when he replied down the phone "I don't have a mustering endorsement. It can't be too hard to get, all you gotta do is chase a few cows around." This stupid statement undid all the positive points I had earlier seen.
Not anywhere on this thread have I seen anyone mention the prime reason for a mustering endorsement: the cattle. No-one on here has mentioned one needs to have cattle sense.
