Great news and thanks the posting! The pundits seem to be mixed about what Part 107 will do for the commercial environment. Some say demand will skyrocket (the FAA, in conjunction with a private consulting firm, predict 100,000 commercial drones by the end of the year and 2.5 million by 2018) while others think it will do little - especially by not taking care of flights above people and Beyond Visual Line of Sight Operations.
Either way, I think it's a big step in the right direction and hope it is a sign of positive things to come in the future.
