This is an awesome idea of course. It's a glimpse into the future.

I remember tweeting with Chris Anderson of 3D Robotics about a year ago about autonomous package delivery from A > B. I'm sure Bezos and team started nerding out on this concept years ago.

Eventually, "vehicles" the size of UPS trucks will be delivering packages autonomously all over the world. This is definitely a glimpse into that day.

And it won't end at just packages, you're going to see food, produce, perishables, medicine (bye bye pharmacy pickups) and many more products delivered to the home via drone.

This is without a doubt the future.

However, like every awesome idea it comes with a boatload of challenges that need to be addressed and I fear some will be extremely difficult if not impossible to overcome.

Off the top of my head, I see a few issues with Amazon Prime Air, some will be resolved, and some won't, but that's the beauty and uncertainty when taking on rather innovative approaches to existing problems.

1. The FAA situation. Drones are going to have _very_ restricted airspace especially in populated metro areas, if the FAA grants them these privileges at all. If you look at Los Angeles/SF/NYC/DC/Boston, you see airspace that is so overcrowded that I just don't see how drones are going to be zipping around here. BUT, most US cities are urban areas, so if we lose delivery to the dense metropolis, this product could work very well. Just like you see in the video.

2. Aside from airspace regulations in popular cities, you have building density, apartments/condos that will make it tough to service (unless these buildings have custom built "delivery stations" somewhere, and that's a cool idea). So it's a glimpse into the replacement of the traditional mailbox. Now that's cool.

3. Package weight will certainly be a concern but Prime Air will still cover an enormous amount of items from Amazon. And I believe Prime Air will allow Amazon to actually expand their product catalog with previously-undeliverable items via traditional freight (food, perishables, medicine, etc.)

4. Humans. Humans are always a problem. You'll have kids/idiots trying to steal and shoot these things down. This is a minor problem that won't necessarily end, but people will get in trouble and they'll pay fines/etc.

5. Safety. Safety is important, Amazon will do whatever it can to prevent kids/adults from getting sliced by these blades but I think that this is inevitable.

6. Hardware failure. Sure, 4 rotors and redundancy. But we all know a few of these things are going to drop out of the sky with a box of wrenches and slam into someones car/face/house/bike/restaurant... That won't be good. But is it even possible to ensure this doesn't happen? Boeing airplanes fall out of the sky...

7. Weather. Be in no doubt these drones will drop left and right, lose course, altitude, etc. with sudden gusts of winds, environmental factors, etc. They're getting better but it's physics at play here.

All in all there are plenty of challenges to an awesome and risky endeavor.

What I don't really understand is WHY. What's the net-gain for Amazon. Will this ever fully replace UPS/USPS shipping for them? Maybe... But it will take at least 20+ years.

I somewhat see this as an experiment for Bezos and company. The R&D and hardware costs far exceed the pennies on the dollar they pay for UPS shipping. But it has that COOL FACTOR to it. It smells like the future. Would you pay extra for 30-minute delivery? Maybe a few times... I wonder about the utility here...
