The original Italian Job and Attenborough's Oh! What A Lovely War - aerials for both by the UK's Mike Smith who runs Heli Air.
For the Italian Job he did the closing scene of the coach hanging over a cliff - which I think he did with an Alouette.
For Oh! What A .... he did the closing shot of thousands of crosses on a hillside above Brighton......I think each cross cost 1s 6d.
