Or the "Amazonoctocopter" fails mid flight over an interstate and drops the package over an interstate. The package falls at a rate of 9.8 m/s^2 or 32.2 ft/s^2 and comes crashing down on a car traveling at 65 mph. The impact to the windshield kills the driver which then causes a sixteen car pileup….good luck getting these approved. Not to mention delivering the package to the house located on short final which causes multiple go-arounds.
