Saw the highlights on the local ABC affiliate tonight. My thoughts were:
Very cool! What a great use for 'copters! Pretty pictures *and* the potential for research data.
and
If they did this in Hawaii, the US FAA would be all over them because ABC News is a commercial operation. But they did it in Iceland, so it was okay.
Grumble...stupid FAA...grumble, grumble....
PS: I went to Iceland 3 years ago...what an incredible place for scenery. If you ever get to go to Iceland, jump on the chance with both feet. You won't regret the experience.
