Thanks for the feedback and voicing your views. Only time will tell what happens. I was just addressing lots of the hype that I saw regarding drones and delivery and how they were going to take over. There are very few in the air right now and already lots of problems with commercial aircraft among other things. I just wanted to layout some of the numbers which in doing so make it hard to imagine.
I appreciate your disagreement and where I do agree with you is that if there is a profitable business to be had then there will be but for the moment I just don't see many areas where that could be the case.
