Yup, I pictured playful cats waiting beneath the lowering packages..lol
I also recommended fisheye cameras digitally record every flight as evidence if anything went awry. Even so, I’d hate to be in charge of such a scheme.
I have a steep driveway and the UPS truck stops in the road then the driver/delivery person jumps out and runs up to place my packages on the porch. If nothing else, the drone could allow a delivery vehicle to station itself centrally to several deliveries, then drone the packages to the exact locations. I see great potential with this. ... Isn’t it a shame that we humans are not better ‘regimented’ to live in neat rows on broad streets, in high towers to concentrate the dwelling spaces and free up the earth for resourtces/food production? (/sarcasm)
