"Under the proposal, most drone owners would have to register the machines with the federal government, which would place the information in a national database, the first such requirements." ----- I hope this doesn't mark the death of the industry, although one could argue that cars went through the same cycle.

While DNA samples would be a great thing to have, I'd hate for that to be the only trance of them left in the future. Imagine one day, when all we will have is a huge book of DNA samples of everything we used to know.
