200 helicopters is incredible - more than some defence forces one imagines.
In my part of the world I can count the number of military helicopters owned by local governments on both hands, sometimes just one hand!
If you're going to get into the rotary business you should know that the US is an anomaly. Lots of stuff going on there that you won't see anywhere else plus they have the world's largest domestic helicopter population.
Another abnormal place is Russia, but you can't do much there unless you are married to a Russian or speak Russian or have a Russian passport, a bit like Brazil.
