This is, errr, a Helicopter...

...and quite clearly the one that we went to the Grand Canyon in. It was fairly pricey ($1000) but certainly worth the cost. We were also given a DVD of the trip (the actual one that we went on) which also included all of the conversations that we had via the headphones in flight. There were also some in cabin views. Depending upon the size of the file, I may try and upload some of the footage to my website. Failing that, I also took my camcorder and I feel quite sure they will be much smaller file sizes.
