Here's another one for the mix.. The R44 with floats was originally going to be called the Neptune (presumably to "rule the waves") but settled down for the Clipper. I guess that the final decision was made over a glass or two of Cutty Sark whiskey? "hey, that's a nice thing on the water on that there bottle, mate, it says it's a Clipper". OK, that's decided then...
the S-76 is also known as the Eagle in military form
the 109 was spelt both Hirundo and Hirondelle dependant on what country the brochure was printed in
I like the nickname Wokka for the Chinook, a very appropriate onomatopoeia which has been used in the domain name
