I am not trying to be mean- you can get rich with your half price airline after you patent your terabyte CD rom system.
You are just ignoring physical reality, because you like your idea- which is fine, I like my ideas, too.
But, consider this- a Predator Drone, which can carry a whopping 800lbs, and has a range of 200 miles, costs about 5 million, not counting the $4 Billion they spent developing it. It requires access to multi-billion dollar military satellite systems, takes 180 people to handle, fuel, fly, and maintain, and requires at least one hour of maintenance for every hour in the sky. The pilots actually need to be BETTER than a run of the mill commuter flight pilot.
Hourly expenses are estimated at a minimum of five to seven thousand dollars per hour in the air, not counting the expenses of the bases and satellite systems that enable it to be controlled.
Imagine the cost multiples to make a drone big enough to fly 200 peoples luggage from Miami to Buenos Aires- and we would be talking many times what a passenger ticket costs.
The absolute cheapest way to fly a plane is with a pilot- commuter airlines in the USA often pay as little as 25 grand a year to pilots. Remote control adds a huge amount to the cost.
And, the drones that the air force uses- the Predators- they have lost over fifty of them to accidents, weather, and just plain unexplained "whoops" incidents- an unmanned aircraft has nobody to notice something going wrong soon enough to correct the problem. The failure rate is far higher for drones than for piloted planes.
the cheapest way to haul luggage would be similar to the way FED-EX hauls packages- with used 757s, which Fed-ex buys for about ten million each, then puts another five million into to make them flyable freighters.
