Re: Hard hats and bridges
Same with you. Lets do an experiment where I get up on the roof of my house, about 20 feet off the ground, and drop a 4.5lb brick on your head and see just how serious your injuries will be.
All do respect, I find your words somewhat non-objective
"Now, as with any complex system, things can go wrong, but there are a lot of redundancies built in. And the drones I fly weigh no more than about 4.5 pounds: In the worst case they would bruise and scratch, but not inflict serious injury."
There are no redundancies built in other than low battery indicators, and return to home gps. What about if one of the 4 electric motors shorts or locks up, or loses a prop? That thing will fall out of the sky like a rock. You said it yourself "complex system"
