Amazon just filed a patent on air dropped packages: http://wetalkuav.com/amazon-parachute-air-drop/

Great, FEDEX didn't break enough stuff, now it's delibery by JDAM I mean JDPD "Joint Direct Package Delivery."

So basically their idea is to use packages that are steerable as they fall, like a JDAM, then either just let them crash into the ground, or deploy a parachute when they are close, the article wasn't clear which. How much will delivery cost? A couple of thousand a box (because of the control unit)? Have to mail the controller back on delivery? I see lots of packages stuck in trees, on (or through) roofs, floating in swimming pools, crashing through windshields, etc. Parachutes do interesting things when the wind hits them, add an AI guidance system and it gets real fun. It's a neat idea but I don't see regular package delivery being done that way. By a drone landing, yes, by JDAM JDPD? No.

That would not work at all in the PNW.

If Prime comes with a LLDR I'm in!

50 Gallons of lube, coming in hot!

Trees, how do they work?

Easily possible and would be a decent idea in some locations. 

Its going to get dropped either way.

Someone really needs to photoshop an amazon box into a JDAM tail.

Can I send a box full of concrete blocks to people I don't like?

I took the FAA exam to be certified as a drone pilot this morning.  There are a number of regulatory hurdles that will prevent Amazon from doing anything until some major things get resolved.

I see grandma laid out on the sidewalk with a large Amazon box on her head.

What could possibly go wrong?

Why?
