According to what I've read, the main drawback to UAV mail delivery is how to ensure peoples safety. You don't necessarly want FedEX UAVs with sharp rotors landing on every door step....but what if the solution was not part of the UAV but part of your home. What if everyone had a chimney that was essentially
just a mail chute and all the UAV did was land on your roof overnight and drop your package down the chute?...at least for packages under 5 lbs (which is most of the mail volume).

This would be appropriate, given that most mail is used as kindling anyways. |

We are wondering how much entertainment we might gain by Assimilating some of these little UAVs. Certainly, the Predators we have taken over are great fun ... |

"And then to top off a bad week, someone put a ferret and a wombat down my package chimbley..." |
|

At least the pear tree broke their fall,
although the ferret has devoured the
partridge … |

I figure the whole UAV mail thing is a farce. If we'd
really wanted to do it, we could have done ballistic
mail sending years ago. As long as the package stays
within a certain weight and size, it could fit into into
a pre-made, padded, heavy sabot that would be
launched to your house. Then again I'm not sure if
projectile calculations are actually accurate to within
like 6 feet like they'd probably need to be if you don't
want to damage anything accidentally |

The calculations are accurate, but the
outcome for large low-velocity projectiles is
unpredictable. The circular error is high,
increasing rapidly with increasing range. |
|
| |
This is because the projectile is not spin-
stabilised, and will therefore "tumble"; since
there wil almost certainly be a disparity
between the centre of gravity and the
volumetric centre, the flight path rapidly
becomes chaotic. |
|
| |
Small variations in wind and air density also
have a large influence. |

For a 1m CEP, terminal guidance is essential. |
