Frank Appel, chief executive of Deutsche Post DHL, told CNBC at the World Economic Forum in Davos that the main obstruction to drone delivery was now governments.
"If governments will allow it - that's the challenge," he said. "In Germany, they are quite conservative, but we operate in many other countries.and territories."
