Cousin isn't the right word............... GREATGRANDCHILD is much closer. The original "Blue Thunder" was a highly modified SA-341 Gazelle. Then there were a at least 2 more generations of Eurocopters and this one (EC-120) came out. They do share the "fenstrom" which is the tail "fan", its safer and more effective than a tail rotor, of course it has a LOT more moving parts. Other than being slower, the EC-120 is about 10 light years ahead of the Gazelle.............
