For the second part of your question, try
this link to a previous thread about Blue Thunder.
But the short answer is: a Gazelle.
I also notice that you're quite new to PPRnNe so you probably haven't discovered the 'search' link at the top of the page. An awful lot of stuff has already been discussed on these boards so you'll probably find the answer to the first part of your question there.
