Running into birds is even harder since the bird has something to say about it
Do you know why it is so hard for them to run into each other?

Default The Big Sky Theory

From Wikipedia:

In aviation, the Big Sky Theory is that two randomly flying bodies are very unlikely to collide, as the three dimensional space is so large relative to the bodies. Some aviation safety rules involving altimetry and navigation standards are based on this concept. It does not apply (or applies less) when aircraft are flying along specific narrow routes, such as an airport traffic pattern or jet airway.

The Big Sky Theory has been mathematically modeled, using a gas law approach. This implies that metal-on-metal collisions of aircraft in free flight should be extremely rare in en-route airspace

Default Drones

Biggest problem for drones that I see is handling weather.

The video mentions a ten mile delivery radius, but having a "mother ship" to act like the current UPS or FedEx delivery trucks could solve that problem.

Cool stuff.

Default Drones??

I thought this was a thread about having your boat in the water not drones.
