This reminds me of a unique pleasure that we had the other day here. It turns out that a rellie of ours marries the daughter of a manager dude from a large HEMS outfit operating in Germany, Austria and Italy. He looks after 40 or so machines on the German operation and 70 odd drivers.
They all turned up here for a day or so, talk about a United Nations, we had around the dinner table, a couple, young poms from sheffield, Two estonians girls, one a scholar of Ag science the other holds a degree in archeology?, a frenchman (ag student), four germans, a canadian girl, four os us oz's and three Mexicans. Well that's what we call Victorians.
anyrate, Gorge the german, had a great day being checked out in Mustering and then doing a check ride with yours truly. he was really impressed with the Robinson and the mustering techniques, absolutely amazed that we didn't just yahoo around like a bunch of cowbows.
He talked about an uncomfortable trip that he had when he did a donk in a BK a few years back, and relevant to this thread, he had to fly in recovery mode at very low level along a very populous section of the Rhine for a good ways, but the company did not draw one noise complaint.
We didn't talk at all about other GA or Private flying, but I will contact him when he gets home and seek his opinion.
