We recently provided aerial footage from our hacked GH2, which was to be mixed with ground shots from a FS100 and 5DmkII, for a Specialized Bicycle web campaign. There was concern (not from me) that the little GH2 wouldn't mix in well with the other footage. We were prepared as always with backup Canon cameras, but after the DP saw what the hacked GH2 was producing, it didn't come back off the helicopter for the rest of the shoot.
Out of the short clips that made the final edits, the shot at 2:49 in this video is one of my favorites:
